Two Black Stones, Different Origins
Black obsidian and black onyx look alike but are different materials. Obsidian is natural volcanic glass—smooth, glassy and conchoidal-fractured. Onyx is a banded chalcedony (quartz) with a matte-to-waxy luster and often subtle parallel bands.
Obsidian
Traditionally a mirror-like protector used for grounding and facing truth. Read obsidian meaning; the obsidian pendant is a sleek everyday shield. Compare it in tourmaline vs obsidian.
Onyx
Onyx is traditionally associated with self-discipline, stamina and steady focus—closer in feel to tiger's eye for willpower than to obsidian's intensity.
How to Choose
- Obsidian for strong protection, release and grounding.
- Onyx for discipline, endurance and a polished matte look.
- Black tourmaline if your main goal is an everyday protective buffer.
