Slim enough to stack with an engagement ring or wear in a ring stack, distinctive enough to stand alone as a wedding or promise ring. Because each inlay is hand-arranged, no two rings are identical.

The base is blue sandstone (also called goldstone) — a glittering deep-blue material flecked with copper crystals that catches light like a constellation. Layered over the top is crushed red fire opal in fragments that flash orange, pink, and red under different lighting angles — the play-of-color fire opal is prized for. Each inlay is hand-arranged before the resin sets, so no two are identical. Want to go deeper on the stone?

The black is bonded into the tungsten alloy itself, not painted, plated, or coated, so it won't scratch off, fade, or wear down to silver underneath. Curious what a black band symbolizes?

This ring won't bend, won't scratch from typing, kitchen work, or daily handling, and won't lose its shape over time — and it's hypoallergenic. Curious how it holds up?
