About the Stone
Onyx is flat-banded chalcedony, the same microcrystalline silica family as agate. Because naturally uniform black chalcedony is uncommon, beads of this even tone are darkened by a long-established treatment that deposits carbon in the stone's pores, which is what keeps a strand consistent. The matte finish is abraded rather than coated, so the colour goes right through.
- Family
Chalcedony (microcrystalline quartz)
- Hardness
6.5 - 7
- Note
Onyx is banded chalcedony - the same layered silica structure as agate, but with the bands lying in flat parallel planes rather than concentric rings. Uniformly black material is uncommon in nature, so most black onyx on the market is pale chalcedony darkened by a long-established sugar-and-acid treatment that deposits carbon in its pores.
