Appreciated by Aztecs and Mayans
Turquoise was highly valued since antiquity. Especially in Egypt and Mexico by the Aztecs and Mayans who used it to make bracelets, amulets and mosaics. Nowadays to find turquoises it is necessary to go to desert regions.
Some historical sites have already been exhausted, while others are still in operation. The extraction of the stones is usually manual, with little or no mechanization. One of the sources of supply of turquoises of greater importance is Iran. And it has been for at least 2000 years, in the time of ancient Persia. From this country turquoises of practically perfect color come from, and they are in a mine located in the top of the mountain Ali-Mersai.
