Turquoise is both the birthstone for December and the official state gemstone of Arizona. The stone can range in color from dark green to a light blue, determined by the amount of aluminum, iron or zinc imbedded within its structure. The spider webbing or dark colorations in turquoise is caused by it hosting or attaching to other stones.
Veins or seam fillings full of turquoise have been discovered all over Arizona and were often occurred near copper mines, making the two resources frequent mining companions. Today, Arizona continues to be a leading producer of the gemstone by value.
While the blue-green stone was used in southwest native jewelry for centuries it was designated the state gemstone in 1974. For a truly Arizona piece, find turquoise crafted into a bola (or bolo) tie – the state’s official neckwear!
