Unfortunately recently some profiteers  by using of fame & popularity of Persian turquoise do some chemical treatments on the Raunchy turquoise stones and change them to colour of Persian Turquoise.

At best This is a difficult task for even those of us who have been around the business for many years. There are many verities of natural and treated turquoise on the market today. Not to mention a myriad of fake and created turquoise. To make matters even worse. There are many different varieties from different mines, which appeal differently to many peoples. Our best advice for those interested in natural and collector stones. Is to know your jeweler, know your source. Use jewelers and sources like ourselves who have been around a long time and intend to stay awhile longer. It will be a better bargain in the long run.

Also synthetic turquoise, frequently chemically perfect, has appeared on the market in some quantity. This is literally stovetop turquoise. It has a very natural matrix created by placing stones in the "batter" or sprinkling in pyrite, etc. When the mix is cut then cabbed these foreign additives, which are real, add to the illusion that the entire stone is natural.

Wax Treated: Much of the turquoise from China is wax impregnated. The paraffin treatment deepens and stabilizes the color but only affects the surface. Turquoise can be rather porous and chalky and is often not suitable for jewelry until it is treated. There are various processes that are used on turquoise.

Stabilization: is a treatment that uses a resinous substance. The process uses pressure and heat to fill the microscopic gaps in the stone with plastic resin. When cured the product is a treated stone hard enough to cut and polish. Stabilization allows genuine but lower grade turquoise to be used in jewelry. Stabilization helps to keep the stone from chipping and prevents changes in color from contact with skin oils.

Wax treatment is very common with turquoise from China. Paraffin wax is impregnated into the turquoise to deepen and stabilizes the color but it only affects the surface.

Some jewelry may be made with reconstituted turquoise which is ground turquoise from inferior stones that is molded together with epoxy resin, dyed and pressed into stone like forms - they look good but don't have the value of a real stone.

Another process is referred to as "Block" where a mixture of plastic resin and dyes are produced in blocks the size of a loaf. There is no actual turquoise in this mix, it is entirely man mad and should be labeled simulated. It is made in many colors, and it is used extensively for inlay work.

"So in the market for turquoise jewelry be aware of what you are purchasing. Simulated turquoise or a natural piece of turquoise jewelry is terrific. What ever your needs are just be certain the product you are purchasing is priced according to its composition. Enjoy this truly captivating stone!!"

One thing that an individual can be aware of is stabilization. A hot pin will give off the smell of the resin and leave a deep mark in stones that are just plastic. Many other false stones such as dyed Howelite or the new stove top synthetics can be very deceiving.
