No thats not the real famous "Persian turquoise"! These are from turquoise from a mine in Southern Iran called Kerman. It was not a source of turquoise until recently because the stone has to get stabilized in order to be cut and polished. The ancient real Persian turquoise comes from the North of Iran from the Neishabour Mine. That mine is said to have been in operation for 7000 years. It produces some of the highest qualities of turquoise which is hard mainly and has a wide range of colors and patterns. It is usually in thin seams and is expensive even in Iran as is in high demand. The turquoise from Kerman can come in very large chunks, usually with a lot of pyrite, and after stabilization becomes a nice blue colour and sometimes you get green too. You can recognize them by their dark color and most of the time with pyrite (while the Neishabour materials rarely have pyrite in them. There are some less known mines in Iran such as Semnan... In Iran, the value of Kerman turquoise is a fraction of Neishabour turquoise. We call stabilized or harmed by oil turquoise a "dead turquoise" while a natural turquoise is called a living stone. I am an Iranian (in Australia) and do sell both. I will have new stocks hopefully soon. A bit difficult to get it out of the country. I also have access to some other rare Iranian stones such as Demantoid, Zunyite, Vary,scite and Iranian Wulfanite.
