Choose your boulder opal, choose your story. Each pendant holds a genuine Australian boulder opal from the Queensland mines, bezel-set by hand in solid sterling silver. Every stone has its own color and its own character, so every setting is shaped around that one stone alone. Raw, rare, and built to last.

Why Boulder Opal

Boulder opal forms inside ironstone in the Queensland outback, over millions of years. The host rock protects the color, which makes boulder opal durable enough for jewelry you actually wear every day. And because no two stones are alike, real opal jewelry can never be mass-produced. In sterling silver it develops a soft patina over time and only grows more beautiful with age.

Care

Store in a dry pouch or box, away from sunlight. Avoid water, perfume, lotions and cleaning agents, and wipe gently with a soft cloth after wearing.
