Turquoise is among the oldest known gemstones - it has been mined since 3,200 BC. It graced the necks of Egyptian Pharaohs and adorned the ceremonial dress of early Native Americans. This robin egg blue hued gemstone has been attributed with healing powers, promoting the wearer's status and wealth, protection from evil and bringing good luck.
Turquoise is an opaque, light to dark blue or blue-green gem. The finest color is an intense blue. Turquoise may contain narrow veins of other materials either isolated or as a network. They are usually black, brown, or yellowish-brown in color. Known as the matrix, these veins of color are sometimes in the form of an intricate pattern, called a spider web.
To improve its color and durability, turquoise is commonly permeated with plastic, a stable enhancement. It is also sometimes permeated with colorless oil or wax, which is considered not as stable as plastic. Some turquoise is dyed to improve its color, but rarely, as this is an unstable enhancement.
One of the treatments to improve color and durability is "reconstitution", wherein fragments of fine turquoise material, too small to be used individually, are powdered and then bonded with resin to form a solid mass.
We use mostly natural, but also some reconstructed turquoise in our jewelry. Most of our natural turquoise is of the purest blue color and comes from the Sleeping Beauty mine in Arizona, which is unfortunately now closed.
