Onyx is a semi-precious form of chalcedony which has alternating straight bands of color, most commonly brown, red, white, and black. Chalcedony is the group name for a large family of stones, all of which form from silicon dioxide, also known as quartz. In order to be classed as chalcedony, a stone must be milky, and translucent to transparent, often with layers or bands of color. The color of onyx, as with other forms of chalcedony, is created through impurities which seep into the rock as it forms.
The most classic color combination for onyx has red or brown bands alternating with white ones. This form is sometimes also called sardonyx, because the red bands resemble sard, another type of chalcedony. More rarely, black bands will be mixed in, or the onyx will be primarily black. Black onyx is highly prized for use in jewelry and ornaments. Other colors can also be found, although they are less common.
To care for onyx, people should take care not to bump or rap their jewelry, as it can cause the stone to crack. Onyx is reasonably hardy, although exposure to excessive sunlight and harsh chemicals should probably be avoided. If onyx is set in a metal, the setting should be checked periodically to make sure that it is not loose. Onyx beads may benefit from periodic cleaning and polishing to remove grime, and should be taken to a jeweler for cleaning.
