REMARK: This nugget is very hard which can be cut directly without any treatment.The webs is compact and the color is fine.A window has been cut out of this Turquoise nugget to give you a look at the natural colors and markings within.Pictures were taken with the stone slightly damp to show true color.

Today the Mineralogists,geologists,miners,and other experts refine a qualitative system for rating turquoise.The primary variables are hardness,color,matrix,rarity and size.We must admit that most of Chinese turquoise is lower grade and must be treated in some way to make it commercially usable.But there still have some Chinese turquoise looks like turquoise from the "classic" American mines.

In China,the main producing area is in Hubei province and Anhui province.The output of hubei turqoise is the largest.The turqoise of hubei mainly concentrate in Wudang mountain,included Yun county, Yunxi county and Zhuxi county which lies on northwest of hubei. Zhuxi county is the main producing area today in china.But the best Chinese turquoise are mined from Yungai mine.This mine located in Yun county,it has been exploited since Tang Dynasty(A.D.618-907), some turquoise in which came down to Europe by the "Silk Road". Turquoise from Yungai mine is the best in China,and the price is very high.Almost all the turquoise dealers know the Yungai turquoise.But this mine was sold to a private company 2 years ago,it has been closed up to 3 years.Most of my Yungai turquoise are sorted from the tailings.

Chinese turquoise are formed in the limestone and the slate.Mostly Zhuxi turquoise are formed in Limestone,they have the mud shell and mud matirx.The color of this kind of turquoise vary greatly,but they are quite fragile.They must be backed with Devcon or other resin before shaping and polishing.Chinese do not like to back the turquoise,we prefer to stabilize the turquoise with clear resin if the turquoise has deep color,this way only enhance the hardness of the turquoise,especially on the mud matrix. Maybe you had noticed that most turquoise cabochons we are selling are stabilized. In China,almost all turquoise dealers consider the stabilized turquoise (not dyed) are NATURAL,it is just the difference of opinion,not someone want to cheat the customers.But we must be aware that if we sell the turquoise to worldwide,natural and stabilized turquoise must be differentiated clearly.

Yungai turquoise are formed in the slate,they have the iron or limonite or pyrite host rock and matrix.This kind of turquoise have high density,deep color,compact matrix,and Yungai turquoise are quite rare now.Tibetan are favourite Yungai turquoise very much,most Yungai turquoise were sold to Tibet directly,only a small quantity of the Yungai turquoise were sold to American.You could hardly find out the genuine natural Yungai turquoise
