Turquoise Gemstones


Turquoise has been mined, traded and valued for centuries and is one of the oldest gems recorded. According to the Geological Society of America, mining of turquoise has been recognized across much of the southwest United States and northern Mexico, including as far north as Leadville, Colorado, and as far south as Zacatecas, Mexico.  Archeological findings of this mineral in Northern New Mexico date back to ca. A.D. 1250-1400.  Today turquoise is mined in many desert regions of the world including China, Iran, Persia, Mexico and the United States.

Since its discovery this precious mineral has been used as a valuable commodity for trade.  Turquoise jewelry is still sold and traded in markets around the world.  Each mine produces stones of various qualities and character which contribute to the uniqueness of the stone, making the turquoise more valuable; such as Cerrillos turquoise from the El Morro Valley in New Mexico or Bisbee Blue from the Bisbee Turquoise Mine in Arizona.  Many of the mines where turquoise was discovered include copper, silver and gold mining activities.

Even today we are still mystified by the beauty of turquoise. These stones come in a variety of colors to include sky blue, blue-green or apple-green, depending on the stone's chemical formula which includes copper aluminum phosphate.  The demand for turquoise has led to the introduction of natural imposters such as dyed howlite, chrysocolla, malachite, variscite and even magnasite so buyer beware because sometimes it's hard to know the difference.

There are tests that can be done but some requires a lab and chemicals  The hardness test may be the easiest for consumers.  A Mohs hardness of 5 to 6 can distinguish turquoise from similar gemstones.  Its hardness can also help identify real turquoise from imitations or synthetic materials.  A harder stone can scratch a stone of lesser hardness.  Quartz has a Mohs hardness of 7, which means that quartz can scratch turquoise.  This is a simple way to determine the genuineness of a stone.
