The stone, in its own words
I’m volcanic glass — lava that hardened too quickly to build a crystal at all. As I cooled, layers of tiny gas bubbles were trapped inside me; that’s the silver sheen you see, and it moves when your wrist does. People have carried my kind for protection for centuries — I offer you the history, not a promise.

Up Close
Flat black at rest. Tilt it, and a band of silver crosses the bead — layers of microscopic gas bubbles, fixed in the glass the moment the lava froze.


A stone bracelet shouldn’t live in a drawer — and this one earns its keep in motion. The 10mm beads sit light and low on the wrist, and every turn slides the silver band somewhere new.
Sized to your wrist — no two strands identical.
Why people keep it on
Wear it with: Yellow Tiger Eye — warm banded gold against the cold silver; both stones work in motion.
From the studio bench
“In the parts tray every bead reads flat black — the sheen only shows when you roll it under the lamp, so we grade them one at a time and keep the ones that throw a clean, unbroken band of silver. And because it’s glass, we handle it like glass: strung a touch looser than quartz, packed to travel in its pouch. First thing everyone does at unboxing is tilt the wrist — exactly right.”
