AI overview
Onyx is a semi-precious stone that is typically black and white in color, belonging to a family of minerals called agate, and it has been valued historically for decorative and ornamental purposes. The term "onyx" is sometimes misused to describe other banded stones like marble or alabaster, but properly refers specifically to the color pattern of the agate mineral itself rather than its band structure.
