Black Sardonyx

Black Sardonyx Tumblestones

This collection features Black Sardonyx specimens recognised for their layered black and white banding and Chalcedony Quartz structure. Sardonyx is a banded variety of Chalcedony formed through successive layers of silica deposition within volcanic rock cavities, producing contrasting colour zones and fine microcrystalline texture.

Black Sardonyx is valued for its sharp banding, smooth surface finish and durability. It is commonly found in polished forms where colour contrast and structural clarity can be clearly observed. This collection highlights Black Sardonyx pieces that display natural band definition, clean polish and well formed Chalcedony structure.
