NAVAJO CLUSTER PENDANT W/ SLEEPING BEAUTY & KINGMAN TURQUOISE
( nugget necklace sold separately)
Is an alloy of silver containing 92.5% by weight of silver and 7.5% by weight of other metals, usually copper. The sterling silver has a minimum fineness of 925.
SILVER, for example 99.9% pure silver, is relatively soft, so silver is usually alloyed with copper to increase its hardness and strength. Sterling silver is prone to tarnishing, and elements other than copper can be used in alloys to reduce tarnishing, as well as casting and fire scale. Such elements include germanium, zinc, silicon and boron.
Sleeping Beauty Turquoise
The Sleeping Beauty Mine, located in Globe, Arizona, is no longer an active mine. For many years it produced a wide range of turquoise that is now even more highly prized for it’s solid soft blue color, with little or no matrix. The color of the turquoise ranges from a deep royal blue to a light sky blue. The mine originally was worked for copper and gold but during the last five decades or so it has produced gemstone quality turquoise in quantities to satisfy the commercial market. In general, the miners lease portions of the “dumps” and sort turquoise from there.
