Not all Turquoise can be gem grade natural, infact most of the Turquoise from the larger mines is mid to low grade. Much of it is "Chalk Turquoise" meaning the stone has not had enough time to formed correctly and to be hard and of good color. This material can be good gem grade material if it is treated. When Turquoise producers complete treatments on the gemstone, they may stabilize, dye, reconstitute, and back the gem. They may also wax and oil the stone.
To stabilize Turquoise, artisans will treat it with a resin which can be water based or oil based. Once the gemstone is stabilized, owners will have a product with greater durability though the value is less than high grade natural, although on today's market there are also different grades of Stabilized Turquoise, some rivaling natural Turquoise in price.
When artisans dye turquoise, they add colors such as blue to the gem during stabilization. With the inclusion of dye, the stone’s color is enhanced as the hue will appear uniform or more intense.
If Turquoise is reconstituted, then an artisan has gathered a large amount of the stone’s fragments, which are too small to be used in a setting on their own. Artisans will then powder the particles and bond them to create one large stone. In some cases, a jewelry piece featuring reconstituted Turquoise will also include fake materials. Therefore, buyers should use caution when purchasing reconstituted products.
Wax and Oil Treatment:
In the past, artisans would wax and oil turquoise, which produced a wet result. After the treatment was finished, the stone’s color would appear bright and intense. When artisans decide to complete a Turquoise treatment involving wax and oil, they typically use high quality gemstones. Keep in mind that a treated stone may sweat when it is exposed to a slight amount of heat or sun, which may cause Turquoise to develop an unattractive white film on its surface.
Often, quality turquoise is discovered in thin veins. With thin gemstones, artisans may glue it to a stronger stone to increase its durability or back it with a lightweight resin. Experts call the process backing. Furthermore, the method allows buyers to acquire higher quality gemstones. Keep in mind that backed Turquoise does not lose its value, often backed Turquoise is more valuable as it is higher grade material. Almost all American stone cutters back Turquoise to show it was cut in America, as well as let the stone sit higher in the bezel. Most Southwestern artists look for backed stones so that they know they are hand cut in the USA.
Turquoise Buying Tips
When shopping for turquoise, be sure to review the stone’s color for vividness and uniformity. After a company procures turquoise, they typically treat the gem to enhance the stone’s attributes. In some cases, treatment will include dye, which will change a pale-colored stone into one with bright colors. Low quality gems usually receive a dye treatment, and since turquoise is porous, it will accept chemically based color additives. If gem shoppers notice that a stone appears translucent, then it may be color treated and is a low quality gem. If a buyer purchases a dyed stone, then he or she should ensure proper care to prevent the turquoise from fading or discoloring. Global turquoise reserves appear to be decreasing while the demand for the gem is growing. Therefore, purchasing a piece of jewelry with a quality stone may be a smart financial investment.
Turquoise is not transparent. Therefore, jewelry cutters typically do not facet the stone. Instead, artisans cut Turquoise cabochons or Turquoise beads. In fact, the cabochon cut is the oldest and most basic way that jewelers cut gems. Buyers will also find Turquoise in carved shapes like pear, flower,heart, and more intricate shapes.

Avoid cleaning the gem with commercial jewelry cleaning products and prevent the stone from entering direct sunlight because it can cause turquoise to discolor.
