Turquoise is found around the world. Historically, it was mined in Iran which was known for striking bright blue stones sometimes referred to as “robin egg” blue. New Mexico, was a big producer in the US until the 1920’s and since then, Arizona is the major producer in the US. Today most turquoise is mined in China and America.

Much natural turquoise is found with veins or matrix running through it. Matrix is the rock material where the turquoise formed. It is a relatively soft gemstone sitting at 5-6 on the Mohs scale so it is susceptible to scratching. Protective settings are advisable.

Almost all turquoise except for the highest grades are stabilized by injecting or infusing it with wax or resin. This improves hardness and resilience in the stone. Some small pieces of turquoise may also be compacted together with a resin binder to make a matrix type turquoise. These are generally accepted provided they are disclosed. There are also numerous simulants for turquoise, most notably dyed Howlite.
