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.

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:
