Gemstone Index: Onyx
Onyx is a striped, semiprecious variety of agate, with white, black, brown or red alternating bands. It is different from regular agate only in that the bands of which it is composed are parallel and regular. The name onyx originates from the Greek word onyx for "fingernail" or "hoof," probably because of its weak transparency or possibly its color. Onyx may chip or scratch rather easily, so store it carefully. Stunning black onyx beads, gemstone donuts, and pendants work for a wide variety of jewelry applications from everyday wear to formal attire. As with nearly all black onyx on the market, our black onyx beads and pendants have been rendered a uniform, permanent black color with a treatment using sugar and acid (and/or heat). This process has been used on the gemstone for thousands of years and is water safe.
