Onyx is a variety of chalcedony that exhibits parallel bands of color, primarily black or white. Natural black onyx does exist, although it is rare. Most of the black onyx on the market has been treated using the sugar-acid method to produce the black color. Natural onyx has long been used for cameos and decorative objects.

History
Most black onyx is banded with white in its natural state. It is dyed to emphasize the banding or to eliminate the banding, based on the stone's intended use. Banded stones are ideal for cameos and carvings. Each creates a unique design and is never exactly like another. Onyx is a chalcedony. It's dyed in pleasing blue shades, crisp greens, bright pinks and even white. Primarily known for its deep black color, onyx is a favorite gemstone of jewelry professionals and consumers alike. Paired with summer whites, black onyx adds sophistication to any look.
Care
Much of the onyx sold today is dyed to enhance its color and to afford you years of enjoyment. As with all color-enhanced stones, clean with warm water and mild soap. Rinse thoroughly and dry with a soft cloth. Do not use chemicals, ultrasonic or steam cleaners.
