Turquoise is a gemstone that has been prized in multiple cultures and civilizations since ancient times. Both the Egyptians, Native Americans and Chinese were attracted to its beauty and some believed it gave the wearer special powers. Below are some tips for getting the best results when shopping for it.

Learn To Separate Authentic And Imitation Turquoise

Authentic turquoisewill always occur naturally, and is a combination of phosphate hydrate and copper aluminum which is formed under extreme pressure and heat. When mined in its raw form it will usually be porous and soft. The distinct bluish green color that is associated with this gemstone is derived from its copper and iron content. However, true turquoise can also be yellow, brown or even black in color when taken from compounds containing copper. Real turquoise will always display a luster which is waxy and opaque.

Turquoise Jewelry Gemstones Have To Be Stabilized

Due to the fact that turquoise in its natural form is porous and soft, before it can be used in jewelry it will first have to be stabilized. This procedure involves submerging the turquoise gemstone in a special stabilizing compound. During this procedure the capillaries of the stones will draw the compound inside it.

There are also a number of enhancements which are commonly made to turquoise. For instance, the AGTA, or American Gem Trade Association has established the various enhancements that can be used with turquoise gemstones. This is important to you as a buyer because you will want to make sure that the seller identifies these enhancements before you buy it.

Turquoise Can Be Categorized Based On Where It Was Mined

Turquoise can be mined in many different parts of the world. However, each location produces specific gemstones that have unique markings and colors. For example, chalk turquoise can only be found in China. It is given this name due to its porous appearance and whitish color, and it has to be specially dyed and stabilized. Chalk turquoise can be dyed in multiple hues of green or blue since the Chinese mines lack the copper needed to give it a natural hue.

Bisbee turquoise can only be found in Arizona. These unique gemstones display numerous blue shades and the stones also display a matrix which is a mixture of red and brown. This pattern can only be seen in turquoise which comes from this area. Persian turquoise can only be found in Iran. These gemstones are exceptionally vibrant and will display a distinct blue color. Unlike Bisbee and chalk turquoise, Persian turquoise does not utilize a matrix.

Always Buy Your Turquoise From A Reputable Dealer

Turquoise gemstones come in lots of different values, depending on its origin. Its cost will depend mainly on scarcity and demand, as some mines have been exhausted. The best dealers to buy turquoise from are those who are members of either the AGTA or IACA (Indian Arts and Crafts Association). This will ensure the product you receive is authentic.
