Black Onyx Tumbled Stone
Black onyx is a deeply opaque, jet-black variety of chalcedony (a form of quartz), traditionally associated with protection and inner strength. This tumbled stone has a smooth, polished surface, a solid, grounding weight in the hand, and a clean, uniform color that gives it a sleek, striking appearance. Because it's natural stone, surface sheen and shape vary slightly from piece to piece.

Care & cleansing
Black onyx is durable (6.5–7 on the Mohs scale) and tolerates handling and brief water contact well. Wipe it with a soft, dry cloth to keep its polish. To refresh it energetically, rest it on selenite, leave it in indirect moonlight, or pass it through incense or sound.
Frequently asked questions
What is black onyx used for?
It is traditionally associated with protection, self-mastery, and inner strength — many people carry a piece for a resilient, disciplined feeling. It is a decorative, symbolic piece, not a health product.
Is black onyx the same as black tourmaline or obsidian?
No — onyx is a banded chalcedony (a quartz variety), tourmaline is a borosilicate mineral, and obsidian is volcanic glass. All three read as solid black stones but have different compositions, hardness, and origins.
Can black onyx get wet?
Brief water contact is fine since it's a hard quartz variety, but there's no need to soak it — wipe it clean with a dry cloth.
How do I cleanse and recharge it?
Rest it on selenite, set it in indirect moonlight, or pass it through incense or sound.
How can I tell if black onyx is real?
Genuine black onyx is a uniform, deep opaque black with a smooth polish and no visible bubbles or seams — dyed howlite or magnesite sometimes mimic it but feel chalkier and lighter.
What pairs well with black onyx?
Many pair it with black obsidian or hematite for layered grounding. Explore more in protection and grounding.
