A genuine Queensland boulder opal, bezel-set by hand in 18k gold fill over sterling silver. Every stone is one of a kind, so every setting is shaped around that one stone alone. This isn't production jewelry: it's a piece of earth that took millions of years to form, finished by hand in Amsterdam.

Why Queensland 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 tougher than soft opal and suitable for everyday wear. Each stone grows its own colors, its own shape, its own fire, which is why real opal jewelry can never be mass-produced. When you wear it, you're wearing something truly rare: a stone that will never exist again, and that only grows more beautiful with time. This is the kind of piece you don't sell. You pass it on.

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. Gold fill develops a soft, warm patina over time.
