NAVAJO CONCHO BELT- STERLING SILVER
ARTIST: LEONARD MALONEY
The word concho, sometimes spelled concha, comes from the Spanish word meaning shell. Some of the first “conchos” were made of melted silver dollars and resembled a shell—it is commonly thought this is how the name came about. In Spanish, the correct word is concha, with an a at the end and is pronounced like an ah sound. However, most people now-a-days refer to the Native American style belt as a concho belt, with an o.

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.
