Navajo Necklace Set – Multi-Color
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.
Spiny Oyster Shell
Living Spondylus shells are, indeed, very spiny, but the polished product looks very smooth, with some of its color variation strongly resembling that of the Blood Oyster. The resemblance is strong enough that it’s important to ask, when purchasing these materials, if they’re from Blood Oyster or Spiny Oyster. Artists often use Spiny Oyster as a substitute for Blood Coral. Although not nearly as rare as the Blood Coral or Rose Coral, divers collect Spiny Oyster by hand, making the work laborious and relatively expensive, with some risks.
The most commonly used Spondylid Bivalve shell colors include orange, reds, and purples and may include distinct striations and color variations. One also finds pink, red, brown, yellow, orange, and white on the market. The Yellow Spiny Oyster’s especially rare.
In the American Oceans, the Spondylids occur along the North American coasts, as far north as North Carolina, on the Atlantic Coast, and northwestern Mexico, on the Pacific Coast. It develops in waters to South America. The Orange Spiny Oyster occurs in shallow to moderately deep waters, where snorkelers and scuba divers readily harvest them. Purple Spiny Oysters grow in deeper water, making them more difficult to find and harvest.

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.
There is a small town in south central Italy, near Naples, famous for its cameos. Their needs for huge quantities of this material over the years have always kept the supply down and demand high. The clear blue is reminiscent of old Persian turquoise, and is without doubt the most preferred and prized by Europeans, both for cameos as well as in bead or jewelry form.
There is a sister mine nearby, called the Bluebird, that produces some of the world’s most beautiful azurite. This material is a copper oxide and also contains malachite, crysacolla as well as a mineralized copper or cuprite. This is a rare and undervalued gemstone that has all but disappeared from the marketplace.
