Precious Spencer Opal Square Ring

Own a precious piece of Idaho history.

This one-of-a-kind precious Idaho opal ring tells a story most jewelry can't: we mined the opal at our family's mine in Spencer, Idaho, cut and polished it in our shop, and set it in solid .925 sterling silver — all under one roof. From the earth to your hand, every step happened right here at our family business.

The centerpiece is a generous 20x16mm square free-form stone with Spencer opal's signature bright play-of-color, cut to follow its natural shape and fire. No two stones come out of the ground alike, so no other ring in the world looks exactly like this one. The opal pictured is the exact stone you'll receive.

And here's the clever part: it adjusts to fit you. The ring is sized at 9, but give the square stone a quarter turn to sit like a diamond and the band opens up two full sizes — comfortably fitting roughly sizes 9 through 11. One ring, three sizes, no jeweler required.
