Medium sized Navajo handcrafted pendant in sterling silver & Golden Hills turquoise
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 standard has a minimum millesimal 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 porosity and fire scale. Such elements include germanium, zinc, platinum, silicon, and boron. Recent examples of alloys using these metals include argentium, sterlium, sterilite and silvadium.
GOLDEN HILLS TURQUOISE:
In the Russian hills of Kazakhstan sits the GOLDEN HILLS mine. The Turquoise is only mined in the winter months during the freezing cold and snow as rains flood the mine during the summer. The location of the mine is remote and difficult to bring equipment in and out of. It is the only Turquoise known to have the unique coloring of bright blue with a Lavender undertone.
Special stone available this year is Kazakhstan Turquoise, or Golden Hills Turquoise. An rare color for turquoise, Golden Hills Turqouise comes from a deposit in the Altyn Tyube mine in Kazakhstan. These stunning gems have a light blue hue to them, and a reddish, burnt umber matrix. The Golden Hills mine is known for producing large quantities of dioptase, a gem very similar to turquoise in color and strength, mimicking emerald in its magnificent green color. The turquoise deposit was found most recently 2013 and was most notably featured at the Tucson Gem and Jewelry show in January of 2014.
