Green Onyx

Q: What is Green Onyx made of?

Green Onyx has the chemical formula SiO₂ (cryptocrystalline chalcedony), crystallises in the trigonal system and measures 6.5 – 7 (Mohs) on the Mohs scale. Onyx is a banded chalcedony traditionally black-and-white; 'green onyx' on the market is either the same banded material dyed green with metallic-salt solutions or, less commonly, naturally green chrome-bearing chalcedony (chrome chalcedony / mtorolite). Both are cryptocrystalline silica — myriad microscopic quartz crystals fused into a dense, opaque mass that takes a mirror polish.
