This can be a broad and difficult subject when we add all the science and all the opinions. I have attempted to group the information in a way that we all can learn a little more about several of the minerals being sold as turquoise and that would sometimes test as a turquoise. The pictures that I have used are just a few samples.
Mineral-“a naturally occurring inorganic solid, with a definite chemical composition, and an ordered atomic arrangement.” Oxford Languages
Is turquoise a mineral? Yes
Gemstone-“a precious or semiprecious stone, especially one cut, polished and used in a piece of jewelry.” Oxford Languages
Is turquoise a gemstone? Yes
Chemistry Periodic Table of the Elements-“a table of the chemical elements arranged in order of atomic number, usually in rows, so that elements with similar atomic structure appear in vertical columns.” Oxford Languages
Chemical Formula-“a set of chemical symbols showing the elements present in a compound and their relative proportions, and in some cases the structure of the compound.” Oxford languages
What is turquoise’s standard chemical formula?
What is a chemical formula variation for turquoise with intrusive iron (Fe)?
Cu(Fe3+, Al)6(PO4)4(OH)8 ∙4H2O
Crystalline Structure-“is any structure of ions, molecules, or atoms that are held together in an ordered, three-dimensional arrangement.” Study.com
Turquoise has a triclinic crystalline structure.
Turquoise is a secondary formation that is deposited into existing spaces of open pockets or crevices within a hillside. The various recipes necessary to create turquoise is a complex composition of copper, aluminum, phosphates, water and oftentimes other available intrusive substances. The acidic water indiscriminately collects all available substances as it flows downward; it dissipates and evaporates depositing the new chemistry into existing seams, cracks, and open spaces within the hillside.
“Any student of mineralogy is well acquainted with what are called “series” of minerals, chemically related substances within which atoms of two different metals can easily substitute for each other in the structure. Such series members are very similar in properties, and often occur close to each other in a deposit as solutions tend to vary somewhat within certain boundaries of that deposit. Such series of related minerals are possible because certain metal ions have similar sizes and other characteristics, so they can interchange.” Bob Jones
“When three mineral species are closely related, they are then shown in textbooks as the three corners of a triangle. The lines connecting those corners represent a gradually changing chemistry as one metal ion substitutes for another in regular percentage amounts. The result is a “family” or “series” of species and varieties.” Bob Jones
The original chemical equation for turquoise defines a pure blue formation with no inclusions or intrusive substances. If we keep this “perfect” sample test in the forefront of this blog post, it will help bring clarity to other turquoise formation varieties, chemistry and comparative mineralogy.
Ferrian is the technical term that refers to most green-colored turquoise. Iron (Fe) is a strong and abundant chromophore that generally becomes dominant when it is brought into contact with a turquoise solution deposit. The Iron (Fe) can replace the Aluminum (Al) within the chemical formula.
This progression of Iron (Fe) will show in analytical tests as chalcosiderite. The solid solution series occurs when more than one element occupies the same space in the structure and substitutes another.
Turquoise Group Minerals
The Turquoise Group has several minerals in its series. Each of these minerals can be similar to one another in chemical formula, but they are not the same mineral, one element can replace another, making a different chemistry.
At each end of the Turquoise Group Minerals spectrum you have specific gems such as Turquoise, Faustite and Chalcosiderite. Turquoise, Faustite and Chalcosiderite in their purest chemical formulas are also visually distinctive and can be specifically identified using good eyesight. I identify formations and cabochons using the visual test for most of these minerals. Turquoise within the lightest blues and greens to the darkest. Faustite cabochons in all the apple green colors. Chalcosiderites in greens, off whites, yellows and some milky white blues. Faustites and chalcosiderites have their own rarity and beauty and are continuing to gain their own grading system and favor among more and more buyers.
Since the water indiscriminately collects and deposits a formation’s mineralogy; a variety of chemical formulas can exist within a single formation. When there is a varied collection of mineralogy it can become complicated to specifically identify the formation into a single mineral class. This is one reason there is so many opinions when identifying Turquoise Group Minerals. These sedimentary formed minerals can have similar chemistry and some visual attributes as turquoise. Especially when these minerals are between chemistry spectrum. In these types of formations, even the world of science has a difficult time specifically analyzing which of the two or three minerals a formation could be identified. One of the most interesting and sometimes rare minerals is when a visual identification can specifically identify two minerals in the same formation.
Analytical Testing and Identification
Minerals with similar structure and somewhat different chemistry can be difficult to identify as one specific mineral without spending some money. The correct scientific tests and the correct interpretation of the tests can add to the expense. The equipment and procedures can be high-tech and specific; identifying every chemistry that exists within one formation. Many times it is possible to identify at least 2 or 3 minerals in one formation when reading the final test results.
1. Only a specific pin-pointed area is tested from a formation. A different area of the formation could be tested with a different result.
2. Different mineral interpretations can be made depending on the qualifications of the person who is analyzing the test results.
3. Sometimes “people” have been known to send in one formation for testing and then using that evaluation paper for a totally different formation.
Why do so many people identify other minerals as turquoise?
We should always ask a salesperson, TV personality, or miner what their experience or opinions are. They probably have a good reason for how they identify the gems they offer for sale.
The following are some of my theories on why most people group so many different minerals as turquoise.
1. Turquoise is the most famous gem in the category of semi-precious gemstones and the Turquoise Mineral Group. Many people do not take the time to explain or learn about the different minerals.
2. Turquoise has so many colors, variety of hardness, and host rock matrix that turquoise itself includes a wide range of properties, therefore many people just identify a few more colors and minerals as turquoise.
3. Turquoise in the American Southwest is absorbed into the amazing Native American history, mystique, and arts. So much so, that if any stone is set in silver Native American jewelry, it is expected that it must be a turquoise.
The tourist often asks: Is this red turquoise?… when looking at coral.
4. Through the last fifty years, turquoise has become rarer and more expensive. Many other minerals have helped fill the demand as comparatively affordable and colorful gems for the market.
5. Most artists are going to use the best available materials to build and use in their art and a lot of the quality turquoise sources have been depleted.
6. Most people are visual buyers. They buy what they like and many of the other minerals are not only beautiful, but they are also rare.
There are many other minerals that can be visually similar to turquoise. These include some of the Turquoise Group Minerals, copper ores, variscites, dolomites,
chrysocollas, azurites, jades and even some larimars along with other minerals. The picture below is just a few colors of variscites.
Buy what you like and if you would like to know if your salesperson has any extra information about the mineral or gemstone that you are purchasing; ask them. There is some really good and interesting information out there about so many unique and beautiful minerals and gemstones. Such as….
1. Faustite was named as a mineral in 1953
2. Variscite not only has a different chemical formula than turquoise, it also has a different crystalline structure. (Al(PO4)∙2H2O)-Orthorhombic
3. A diamond and turquoise are each Triclinic in their crystalline structures.

I don’t Like Turquoise BUT I love everything else about it
When I was around eight years old my grandfather gave me my first piece of turquoise. It was a natural high dome, high grade Persian cabochon. I loved my grandfather and he loved me and he was taking the time to share with me his greatest passion outside of family. Grandpa was loving and hospitable; warm and so gentle in his personality. I tried my best to respond to his gift with respect and love. He was shocked and a little hurt that I was unimpressed and thought the turquoise was ugly and its colors loud.
He was a wonderful grandpa and an influential man in my life, but I don’t think he ever quite knew what to do with a grandson who didn’t like turquoise.
I believe the ways that I began to compare and define turquoise to people was influenced by my grandfather’s unending passion for turquoise. I could relate to his passion about turquoise when I realized that most people in turquoise were colorful and passionate just like he was. To me, it is just turquoise. Yet to others, it was a personal journey of discovery, color and people. I discovered that people are as colorful as turquoise; each one unique. The variety of opinions about turquoise was all over the map. Everyone was ready to defend their personal favorites of colors, matrix, mines, miners, artists, art, lapidarists, geology, mineralogy, mystical qualities, opinions, culture, history, and the list goes on and on. I discovered that these people and their variety of opinions fascinated me. How could one gemstone fulfill so many people’s unique passions and opinions? I began to recognize that the story of turquoise was one of the greatest untold subjects in the history of mankind. It is a never ending study of every subject in the history of the world. Here a just a few.
It is a gemstone. Okay. Define the gemstone. Is it white, blue or green? What is the chemical formula when it is green compared to blue. How can Bisbee and Number Eight and Manassa all be the same gemstone.
It is a color. Okay. Which color is it? Is it sky blue or sea green or another? It is the only color that does not stay in a color range like reds, oranges or purples.
Teaching the English language
Reading/Spelling-To learn the English language you will need to understand the (Q –U rule)
the (double vowel rule) and the (silent E rule). The word turquoise has all three. Turquoise can also be used as a nown or an adjective.
Geography-Turquoise deposits have been discovered on 6 or 7 continents. There is a country in South America that has turquoise deposits. Don’t know which one. This country has the same name and similar shape to what makes New Mexican food hot.
Mineralogy- Why does iron make red colors but iron make turquoise green? All mineralogy and science can be taught using turquoise.
History-Turquoise was one of the first, if not the first minerals used for ornamentation. This includes the arts, history and cultures all over the world. Pick a culture and learn about their uses of turquoise and trade.
Imitations-Learn about science and mankind’s wonder and abilities to create what they see. Concrete was not invented as an imitation for turquoise. But concrete can be shaped and enameled to imitate turquoise.
Human Nature-See anthropology (the study of human behavior) come to light when anyone studies or gives an opinion about turquoise.
Religion-Now here is a fun subject to learn about using the subject turquoise.
Math-weights and measures is math. Buying a piece of turquoise can include all forms of math.
Geometry and more…
Turquoise is the most FASCINATING gemstone in the world!
These are just some of the reasons why….
I don’t Like Turquoise BUT I love everything else about it!

The Trade of Turquoise in the Western Hemisphere
For over twenty five years I have discussed and written about my theory that turquoise trade in the
Western Hemisphere is regional. I have spoken at symposiums, written papers and books that have included different aspects of why turquoise trade is regional. Thankfully, over the last ten years I have found a little more reception to my studies from the academia world. Some archaeologists have even used parts of my theory to help develop their own studies. I still believe that the true history of trade in the Western Hemisphere needs to be restudied and rewritten in more aspects than just turquoise.
I have always appreciated all the different people who have helped me through the years. The study of
turquoise takes everyone! It is amazing how many people or institutions owned a mine site, an artifact, a story, specific information or even ideas about the past. Sometimes it is difficult to not offend someone or an institution when you use their information or their artifacts in conclusions that disagree with their conclusions in their own studies, their books or their turquoise related businesses. Anyone who knows me knows that I think turquoise is bigger than any one person’s knowledge and bigger than science. I have made my fair share of mistakes in my studies but continue to learn. Please enjoy this blog. This blog is so long that I included some pictures to keep you entertained.
The study of human behavior in social, cultural and linguistic situations is sometimes the most important
tool when studying past cultures, written documents and books about turquoise. In life, we as humans can arrive at different conclusions using the same information. We can ignore information that does not fit our agenda, beliefs, values or ideas. Many times we are predetermined to think about turquoise in certain ways. Where and who we get our turquoise information is important but not always correct or complete. Our initial influences are powerful factors in how we think. Some of us look at turquoise scientifically; others look at turquoise culturally, while others just like the color turquoise as an accent in jewelry. There are so many ways that we can all enjoy turquoise.
The following information shows how past information in interviews, books, artifacts and scientific information can all be used to create a bigger study about turquoise and turquoise trade in the Western Hemisphere. I will also show how exaggerated stories or misinformation is continually quoted by the scientists.
How is the Information Gathered?
To understand the information available for the research of turquoise we must understand that information and the collection of information involves people. We are all a little passionate and colorful when we share what we know or heard about turquoise. The following discussion is to show how I came to question some of the documents, books and past information about turquoise. I have been asking if the following general statements are true and researching what influence these statements, books and assumptions have had on today’s accepted history of turquoise trade in the Western Hemisphere.
Why was the Cerrillos mining area established as the only logical location for all turquoise artifacts discovered in the western hemisphere?
∙The Spanish conquerors located Santa Fe as a capitol.
∙Friar Marcos de Niza wrote about great turquoise ornamentation and value.
∙The Santa Fe Trail ends in Santa Fe.
∙The Hyde Expedition documented the Cerrillos area.
∙George Kunz understood and wrote about the value of the Cerrillos turquoise.
∙The United States became the center of university classes, influence and perspective from the white European perspective all over this hemisphere.
∙Joseph Pogue wrote his fabulous book Turquois, in 1915.
No other turquoise mine is written about with as much veracity and continual romance as the Cerrillos mining areas. As the world continues to discover more turquoise sources and artifacts around the western hemisphere; certain archaeologists and researchers continue to quote the cookie cut past written information with themselves having limited or no source turquoise knowledge? This adds to the confusion about turquoise.
Directions traveled, destinations written about, romance, final locations and people all influenced how the Cerrillos area turquoise mines became synonymous with turquoise trade in the Western Hemisphere. How would we determine if the information and conclusions are correct that we hear and read? How influential was the printing press, culture and tourism in the information that is accepted.
I have a Few More
Why did the Mesoamerican cultures travel thousands of miles to get turquoise at what is now Cerrillos?∙Traveling from Mexico City, Mexico to Santa Fe, New Mexico is 2,343km (1455.873 miles) using a direct modern road route.
∙Where did the Mesoamerican cultures get their jade, spiny oyster and mother of pearl. Spiny Oyster comes from the Gulf of California.
∙Did the Mesoamerican cultures already have the interest and ability to mine jade and other rocks?
∙How primitive were the people that crossed the Bering Land Bridge? Do humans forget information? If the Land Bridge is the source of migration 15,000 years ago. Why is there no Bronze Age until Nazca culture in the South? Why did the people in the Northern part of the Western Hemisphere not develop as other cultures around the world? Did their brains freeze from the cold crossing? Why did the cultures in what is now North America not develop metallurgy?
∙ Why is the Europeans value system of blue turquoise now accepted in Native America? Most ancient southwestern artifacts are green, green blue or blue green.
∙What is the original definition of the word chalchihuitl? Did the Nahuatl language differentiate between jade and turquoise/green or blue?
What if the Spanish or the easterners had come from a different direction? (North, West or South) (Anasazi Park, Utah; Stone Hammer mines, California; Paquime, Mexico; Swarts Ruin, New Mexico; Snaketown, Arizona,and many other locations.
∙Do we comprehend what we read? The Hyde expedition refers to a one-hundred year old pine trees and lichen covered rocks on the top of and/or in the bottom of the dumps of the Mount Chalchihuitl area. (1857 A.D. -100 years =1757 A.D.) Lichen grow 1 to 2 mm per year. Evidence of stone tools can be right next to metal tools when a stone wall collapses.
∙Do we believe in science? Turquoise is a water-based mineral. It does not do well with heat. Building a fire along a wall of turquoise and then throwing water on the heated wall does not encourage any of the turquoise to be usable when you are finished using this old wives’ tale.
∙Who were Friar Marcos de Niza, George Kunz, and James McNulty as personalities and what was their interest in turquoise?
∙How many papers have been presented about turquoise identification (fingerprinting) and trade that have proven to be false? Thankfully, this continual misinformation has thankfully helped build tourism in New Mexico.
What we do Know?
- There is enough technology, modern knowledge and transportation to study turquoise.
- The study of turquoise will take everyone working together.
- There have been many mistakes made in developing information about turquoise. Every time I make a presentation or write, I learn, add information and correct other information.
- The following discussion points will show some issues in turquoise writings, books and research that has influenced a few “conclusions” through the years.
- Friar Marcos de Niza, George Kunz and James McNulty gave out a lot of information that I believe was not scientific or correct.
- The Cerrillos area is most people’s starting point in the Western Hemisphere to write about turquoise.
Even The British Museum!
British Museum, 2006
Published a book by Colin McEwan and others concerning a new scientific study of their museum’s nine Mesoamerican artifacts.
Not one Mexican mine site was studied or mentioned. In the modern era (2006) How can any study be scientific; if the science they are using is wrong and multiple known mine sources in Mexico are not part of a study about Mexican sourced artifacts?
In Pogue’s book published in 1915: Within the Introduction it states, “No large deposits of turquoise have been found in Mexico or Central America that would supply the quantity needed for the many items that have been found, or which must still lie buried.”
There is plenty of turquoise mine sources in what is now the countries of Mexico and Chile.
Most people who write books or have information about turquoise only know a sliver of information. A miner knows their mine. A cutter knows the trade of lapidary and the sources they have cut. A retail store owner knows their merchandise. Everyone can read a book, but who did the author interview to get the information and pictures? How does the author or the future researchers know the information is correct?
Turquois, Joseph Pogue (1915) Tiffany Blue, Patricia MaGraw (2006) The Great American Turquoise Rush, Philip Chambless and Mike Ryan (2016)
George Kunz and James McNulty each continually stated that they get $200,000.00 per year of turquoise out of the Cerrillos area.
Two million dollars worth of turquoise was produced out of the Cerrillos area in one decade (1890-1900). It is stated over and over in books and has influenced how researchers use the Cerrillos area historically and currently. Turquoise trade, uses, productions, qualities and prices are all referenced using this type of information in books. But is all of the information true? What occurred at the same time that the turquoise production and value increased in 1891? Human nature is the clue for the answer. Sometimes people might have ulterior motives. Gasp.
Turquois, Pogue (1915) page, 135 “From this point of view the output of the Cerrillos deposits alone from 1890 to 1900, the period of greatest productiveness, is estimated at $2,000,000.00;” This time, this specific quote is from George Kunz.
Where is the evidence? Riches? Houses? Secured barriers to the mines?
In 1900 $2,000,000.00 is equivalent to $61,240,000.00 in 2020.
In 1900 the price of gold was $20.67 an ounce.
Kunz is saying that 1 carat of turquoise is essentially worth half of an ounce of gold.
There is 5 carats in 1 gram/There are 28.35 grams in 1 ounce
If 1 carat of turquoise cost $10.00, how much is that per ounce?
I ounce of turquoise would equal 141.75 carats
141.75 carats of turquoise sold at $10.00 per carat equals $1,417.75
With inflation in 2018 that is $43,179.65. 1 ounce of gold was 20.67.
Where are the riches, houses, and secured barriers for gold mines and those connected to the gold industry? Where is the evidence for this type of production and value in the turquoise industry? Zero
The Great American Turquoise Rush 1890-1910, Philip Chambless and Mike Ryan (2016) page 43
“During the 1880s, all mining activity in the Cerrillos District was directed toward finding gold and silver. If turquoise was found, it was ignored because the price for the mineral was so low it did pay to bring it to market.”
What changed in 1891? Page 42
“In 1880, New York stock promoters hired a Yale University geology professor named Benjamin Silliman to prepare reports on Mount Chalchihuitl and other New Mexico mining properties. He was considered a mining authority and charged top dollar for his services. In exchange, he had a tendency to exaggerate the facts in the interest of his employers. Silliman’s articles were used to advance the fame and stimulate stock sales in the East.”
Who was pushing the agenda that Cerrillos had great turquoise and a lot of it?
Friar Marcos de Niza, George Kunz, Benjamin Silliman, and James McNulty are who the writers, newspapers journalists and investors were listening too. Many of the Santa Fe archaeologists are still listening to them.
Tiffany Blue, (2006) page 139
Sometimes when we exaggerate we can get ourselves in trouble. Especially if a lawyer asks us about our exaggerations in a court of law.
Lawyer Clancy- “at the time Sena and Purdy were down there, at the time you spoke of–didn’t you tell Mr. Purdy that you were getting two hundred thousand dollars out of the mine?”
McNulty-”I did, and I have told others besides, anybody who will ask me—How much did you get out of here, I says, I will not put it under two hundred thousand dollars.”
Lawyer Clancy-”Don’t you think now that since the time you there to work that you have taken out and shipped away about five hundred thousand dollars’ worth of stones?”
McNulty-”That I do not say. I do not know anything about it. I am under oath now.”
Is there any turquoise evidence that what they said or the Cerrillos Agenda Apologists are saying today?
I think some of what is said is true but the overall story of trade and production and value is not. A miner friend of mine uses two words to describe the Cerrillos area’s written history and production, “boondoggle and incredible”.
Tiffany Blue, page 32
The information that can correct a lot of the Cerrillos exaggerations is right there in existing books.
May 25, 1899-”I cannot find any better specimens than last shipment to stop work. The box contained plenty of good color. But there was not a single piece that we could make any use of.” Tiffany’s was not making “Indian” jewelry. Tiffany only needed stones the size of 1 or 2 carats.
Page 15-”By 1895, Doty pressured McNulty for more stone and better results.”
Page 68-”McNulty regularly received letters telling him the turquoise he sent wasn’t worth much.”
Page 75-”They average a cigar box of turquoise per week”
Page 15-”Each box contained about five pounds of stone.”
Page 52-”a cigar box being worth, as we were told, as much as” $10,000.00”
Page 100, August 13, 1901-”we are in no better condition than we were three years ago.
According to my research, the Cerrillos area mines were more about investor’s money than the production of turquoise. Maybe I am looking at the wrong information and need some help to see more information.
Turquoise, Gem of the Centuries, Oscar Branson, (1976)
Page 43 and 51
This book has so much to do with winners writing history and creating influences for the ages. It was the first book to showcase “American” turquoise in color photography. The nightmare occurred when the author and others had to deal with reality. America’s most famous Cerrillos turquoise area did not have the production or the quality that had been written and marketed for so long. Whereas other cultures and turquoise histories were defined by a grade of turquoise, the American market defined the specific mining area by a name first and not by a conformed grading system. How does America’s most famous mine stack up to the standard of the Persian blue turquoise and the history and influence that Tiffany’s starting promoting so many years ago in the Eastern United States.
The world expects gemstones to have conformity and they generally see quality turquoise as only blue with clarity and no matrix.
Not every mine produces turquoise of the same quality of the Persian turquoise. This Cerrillos picture shows how the problem of average turquoise was solved: They just added Persian and Tyrone turquoise to the picture. Who was going to know the difference? Now! According to this picture; the Cerrillos turquoise from New Mexico is just a good as Persian turquoise from Iran! Now that is marketing!
Why did Oscar Branson choose the nice oval turquoise with clarity to be the “classic” from Cerrillos?
They were trying to compete with the famous Persian blue.
Why did they put Persian turquoise in the picture as Cerrillos turquoise?
Why did they put Tyrone turquoise in the picture for Cerrillos turquoise?
At least it was from New Mexico.
Why did they use such low grade Tyrone turquoise for the Tyrone picture?
They couldn’t afford for the Cerrillos area mines to not have the best turquoise in New Mexico.
I went to Cerrillos Day a few years ago at Turquoise Hill. The Santa Fe archaeologists group had a huge banner up about their turquoise event. They used a picture of a specific Mesoamerican mask as the center piece. At that time the archaeologists did not know that only the bottom eyelids are inset with turquoise. When I informed one of the archaeologists about the eyelids his response was….Please do tell anyone.
To the New Mexico Archaeologists in Santa Fe and Their Colleagues
Over time, some New Mexico archaeologists began agreeing with me that Cerrillos is not the only source of turquoise for artifacts from places such as Chaco Canyon, other sites and what is now Mexico. At one of their last presentations that I attended I was astonished at their lack of science, credits and conclusion. They analyzed a grouping of turquoise samples from a archaeological dig site. Their conclusion was that a few pieces of turquoise from the pile were from one mine source and a few more were from another mine and a few more were from another mine source and so on. They determined that the turquoise samples were from a variety of mines including Nevada, California, Arizona, New Mexico and Mexico. Seriously! Did these ancients go selecting different kinds of turquoise while shopping at the turquoise isle at Walmart? I’ll take one of these, 3 of these and 9 of those. Urgh.
What if most of our interpretation of the history of turquoise is incomplete or wrong?
Cool. Our future generations will have something to do.
∙We are human and have made human errors. Such as trusting that everyone who has been interviewed or wrote something about turquoise new all the facts.
I know I don’t know all the facts. It will take everyone. Even some of us who have been wrong in the past.
∙We have limited science and have continued to jump to conclusions that are incorrect.
∙What can we do?
Let’s get the artifacts, data bases and science that we do have; correctly cataloged for future generations. If we have time and the correct science to finish the study….Cool.
- Most past and current information about the Cerrillos mining area is more about repeating and marketing than research?
- How did the Western Hemisphere start from the North and develop South?
- People are people. We all have a part and we are all somewhat colorful.
- Anthropology is more important than finger printing turquoise.
- Historically the turquoise trade in the western hemisphere is regional.
- Turquoise is greater than science.
- There were other American turquoise mines that were supplying Tiffany’s.
- Today’s Native American appreciation and marketing of bright blue turquoise is a twentieth century phenomena.
The American Southwest has some of the greatest people and resources to study the history of the western hemisphere. I believe that the Western Hemisphere history of trade has never been completely studied or written. I believe this is a positive statement. It is an energizing and fascinating statement. If it is true that the winner writes history? The current history was written and interpreted by Spanish and American European influenced people. If it is true, that science is impartial: Then everyone who reads this blog should be excited to look into new studies of the Western Hemisphere as it relates to turquoise and trade.

Is Turquoise Rare?
The answer is yes.
Turquoise is one of the rarest gemstones in the world.
Rare- (of an event, situation, or condition) not occurring very often.
(of a thing) not found in large numbers and consequently of interest or value.
Unique-being the only one of its kind; unlike anything else.
Let’s compare the rarity of turquoise to diamonds
Travel the world or attend the Hong Kong or Tucson gem shows.
Then ask yourself:
How many diamond stores in or nearby every mall in the world? Four or five?
How many diamond stores in every town in the world?
How many turquoise stores in every mall in the world? None
Supply and demand- Supply refers to the amount of goods that are available. Demand refers to how many people want those goods. The demand for diamonds is great and needs a gemstone that is not the
rarest to supply such a massive market. How large of a supply of diamonds does it take to supply the mass amount of diamond stores in the world?
Turquoise supplies a much smaller market. By definition of rarity (not market size) turquoise is rarer than diamonds.
Diamonds deserve their place in the world of gemstones as a commerce gemstone. They are an easy gemstone and subject to learn about and grade. They are common enough that anyone can be taught to be an expert within a qualified class study.
Turquoise is a rare gemstone with many one of-a-kind formations that can take a lifetime to learn. The gemstone turquoise is not about conformity but about rarity and uniqueness. Photography is slowly changing the world’s collector’s appreciation for what is rare. Unique is defined as one-of-a-kind and there are many forms of turquoise that are unique.
But, they say a diamond has a hardness of 10 and turquoise is a soft gemstone. The discussion is what is rare not which gemstone is harder. A painting by Picasso or Monet is not a 10 on the hardness scale, but they are rare and will need to be properly cared for. The cool thing about a diamond is that you can wear it forever and not worry about a thing ever happening to it. If you lose it, you can even buy another one just like it.
The world is becoming aware that turquoise’s rarity is defined by the gemstone itself and not by a culture’s uses of turquoise in their arts or by comparing turquoise to other gemstones.
It is through the scientific study of the geology and mineralogy of turquoise that its true rarity and varieties are defined and appreciated. For generations, many in the gemstone community have diminished turquoise’s monetary value and gemstone standing by negatively comparing turquoise’s inconsistencies of its colors, the intrusions of other minerals, and its medium hardness to other gemstones such as a diamond. Turquoise is a rare and collectible gemstones specifically because of these so-called inconsistencies.
A specific geological area and its available mineralogy are what determine the size, density, harness, color, intrusions, and specific chemical formula of turquoise. As each of these diversities in color, clarity, matrix, and source have become scientifically identified and cataloged by picture, the rarest of
these categories have become collectibles.
Natural turquoise is one of the rarest gemstones in the world.
In my opinion: If someone counted all the imitations that have been made of turquoise through the years, they would discover that all of the imitations of turquoise are actually rarer than all the natural diamonds.
