Gemstone Factoids: Onyx
31 07 2008
Onyx is a form of quartz. The colors of its bands range from white to almost every color. Specimens of onyx available contain bands of colors of white, tan, and brown. Pure black onyx is common, and perhaps the most famous variety, but not as common as onyx with banded colors. It is usually cut as a cabochon, or into beads, and is also used for intaglios and cameos, where the bands make the image contrast with the background.
If onyx is cleaned with an ultrasonic device or cleaned with abrasive or ammonia based chemicals, discoloration of the stone may occur. So be careful wearing it when using cleaning solutions around the house.
The luminous, glow of cultured freshwater pearls is the perfect contrast to rich black onyx in this dramatically elegant Cultured Freshwater Pearl and Onyx Sterling Silver 16 inch Necklace. It’s a classic strand lovely enough to be worn with any outfit.
