Black Agate vs Black Onyx: What is the Difference?

1) Definition

Black agate and black onyx are both varieties of chalcedony, a microcrystalline form of quartz. However, their formation processes differ:

• Black Agate: Formed through the deposition of silica in volcanic cavities

• Black Onyx: A type of agate with parallel bands, often artificially treated for uniform colour

2) Line Structure

The line structure is a key differentiating factor:

Characteristic	Black Agate	Black Onyx
Pattern	Irregular	Parallel
Bands	Curved	Straight
Consistency	Varied	Uniform

3) Luster

Both stones exhibit a similar luster, but subtle differences exist:

• Black Agate: Waxy to vitreous luster

• Black Onyx: Greasy to vitreous luster

The luster can be enhanced through polishing, making identification challenging for the untrained eye.
