Product Description


The Dry Creek mine is a small mine located in Lander County outside of Austin, NV. Sometimes referred to as Sacred Buffalo turquoise, the Dry Creek turquoise mine was discovered in the early 1990s by the Shoshone Indian tribe. When it was discovered, cutters were unsure that it was actually turquoise due to its unique color, but later lab testing by the current owners in 1999 confirmed it was indeed turquoise.

Turquoise gets its color from the presence of heavy metals, particularly aluminum and copper. When there is more copper, blue turquoise will usually be produced as is the case in most Arizona turquoises. When there is more aluminum, green turquoise will be produced as in many of the Nevada turquoises. Dry Creek turquoise forms in any area with low concentrations of both metals. This very rare situation results in the very pale blue color found in Dry Creek turquoise. Most pale blue turquoise is chalky and too soft to cut without stabilization. Dry Creek turquoise is naturally hard and takes a nice polish, so no treatment is needed. No other vein of this material has been discovered anywhere in the world.

After the owner’s passing several years ago, material from the Dry Creek turquoise mine became scarce due to family disputes. Most of the quality Dry Creek turquoise on the market today was mined back in the 1990’s.


Kingman


The Kingman mine in northwestern Arizona was one of the largest turquoise mines in North America. The terms “Kingman” or “high blue” refer to the blue color usually displayed in this stone. It has become a color standard in the industry. The mine became famous for its rounded, bright blue nuggets with black matrix. Few turquoise mines produced nuggets, especially of this quality. Old natural Kingman Turquoise is rare. The Colbaugh’s own this mine and the Turquoise Mountain mine, their company name is Colbough Processing. They have recently gone back into the section of the Kingman mine and are digging and bringing our some new Natural Kingman Turquoise.


Sterling silver

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.

Oxidized silver ( black coloring in the silver ) is a process that many jewelers use to give sterling silver a black patina. It gives the jewelry an antique or tarnished look. The process consists of taking clean sterling silver and using a chemical (liver of sulphur) to treat it to speed up the tarnishing effect.
