Black Onyx
Onyx is a silicate, parallel banded mineral of layered chalcedony. Onyx that is white with distinct black parallel bands is rare and valuable but most of it that is sold is fake having been modified by dyeing or treating other parallel banded stones. No bands are visible in the stones we sell and they are a uniform black colour.
Agate and Onyx are both forms of banded chalcedony which are translucent in thin slices. This translucent nature is a feature which distinguishes agate and onyx from jasper (jasper is always opaque meaning that light does not pass though it). Due to the thickness of these stones they appear opaque and only thin slices of the stones will appear translucent.
Description of Black Onyx
These stones are genuine onyx but lack distinct parallel bands. They are predominantly uniform black. (Highly valuable onyx is white with distinct black parallel bands.)
Due to the thickness of these stones they appear opaque and only thin slices of the stones will appear translucent.
These stones have been fully tumbled to develop a smooth polished finish.
