In fact, turquoise’s varieties are sometimes also categorised by their origins! Below are some of the more popular origins of it.

Arizona – Both Mojave Turquoise as well as Sleeping Beauty Turquoise are being mined from the state of Arizona, USA. Sleeping Beauty Turquoise is called so as the mountain from where it is mined resembles quite closely to the shape of a woman lying on her back with her arms closed. The mine started operating about 40 years ago, when it was dug up to locate copper and gold. Other source in Arizona itself is Arizona Kingman Mine, which is popular and famously known for the rare, prized, and extraordinary Mojave turquoise.

Iran – Previously known as Persia, the country is extremely popular for its finest grade of the said gemstones. Persian turquoises have an exceptional brilliance of both colour and texture. These extraordinary features are the reason why they are counted among the most expensive varieties of the stone. Major mines of the jewel are located near the city called Nishapur.

How is Turquoise Mined?

The procurement of turquoise is usually done using heavy machinery. Light explosives are used to break the surface of Earth and promising veins are located that might carry the beautiful gem. Then the rubble is raked and small rocks carrying the stone are collected. Even though using dynamite and other explosives offers a higher yield, it is destructive if you wish to locate bigger sizes. Turquoise has stability that is only a little bit more durable than that of glass, so explosives cause damage to the size.

Commercially, only a single location has been placed in Iran, from where they mine the beautiful gem, and it is located in a small section of Ali-Mersai Mountain Range, which lies just on the outside of the city called Mashhad. More turquoise is mined from popular locations in Arizona as well as Nevada, where the gem is only the by-product of mines that are dig up to locate copper and gold.
