Obsidian is not a crystal at all — it is natural volcanic glass, cooled too fast for any crystal structure to form. That origin is exactly what tradition prizes: a stone born of fire and pressure, dark enough to see your reflection in, worn for millennia as a mirror against negativity.
What is obsidian?
Obsidian forms when silica-rich lava quenches rapidly, producing an amorphous glass around 5 to 5.5 on the Mohs scale with the conchoidal fracture that made it humanity's first blade material. Our silver obsidian is the sheen variety: layers of trapped gas bubbles scatter light into a silvery, moonlit glow that moves across the bead — the "meteorite" look our bracelet is named for. Major sources include Mexico, the western United States and Armenia.
What does obsidian mean in Chinese tradition?
黑曜石 (hēiyàoshí) is the classic grounding and protection stone. Tradition reads its dark mirror surface as absorbing and deflecting negative influence, and its volcanic birth as compressed strength — worn to stay rooted when circumstances shake. Buddhist carvers have long favored it for guardian figures. In the five-element system its deep black belongs to Water, the element of depth and composure. As with every tradition we relay: cultural belief, told honestly, promised as nothing more.
Silver sheen vs. black obsidian — what's the difference?
Plain black obsidian is uniformly dark; silver sheen carries those bubble layers that flash silver-gray as the stone turns. Same glass, same tradition, different character: black reads as formal and absolute, silver sheen as subtler and more atmospheric. Rainbow and gold sheen varieties exist on the same principle with different layer chemistry.
How do I care for obsidian?
Glass is tougher than its reputation but hates impact: a hard knock can chip it where quartz would shrug. Remove it for gym sessions, store it away from harder beads, clean with a soft cloth and lukewarm water. Sheen obsidian's glow needs no maintenance — it is structural, not a coating, and cannot wear off.

Frequently Asked Questions
Is obsidian a real crystal?
No — obsidian is natural volcanic glass, cooled too quickly to crystallize. That is not a defect: its glassy conchoidal fracture made it humanity’s first blade material, and tradition prizes its fire-born origin.
What makes silver sheen obsidian shimmer?
Layers of microscopic gas bubbles trapped as the lava cooled scatter light into a moving silver glow. The effect is structural — it cannot fade or wear off.
What does obsidian protect against, traditionally?
Chinese tradition reads its dark mirror surface as absorbing and deflecting negative influence, and wears it for grounding. This is cultural tradition, not a factual claim.
Is obsidian fragile?
It wears well daily but, being glass, dislikes sharp impacts — remove it for sports, store it away from harder beads, and it will last for years.
