Sterling Silver Aquamarine, Smoky Quartz and Onyx Chandelier Earrings

Onyx is a chalcedony quartz with a fine texture and black color. Some onyx also displays white bands or ribbons against a black background. Onyx was popular with the ancient Greeks and Romans. The name comes from the Greek word "onux," which means fingernail. The myth is that Cupid cut the divine fingernails of Venus one day while she was sleeping. He discarded the clippings and the fates turned them to stone so that no part of Venus would ever be lost. In Greek times, almost all colors of chalcedony from fingernail white to dark brown and black were called onyx. Later, the Romans narrowed the term to refer to black and dark brown colors only.

The relatively abundant mineral smoky quartz ranges in color from almost black to nearly colorless. Gem quality specimens are mined from the Swiss Alps and from Pike's Peak in Colorado. Dark smoky quartz is sometimes heat-treated to give it a lighter color which appears more brilliant when cut.
