Collection: Black Opal Gemstones

For collectors and for custom commissions, a loose black opal is where it all begins. Each stone here is hand-selected for body tone, brightness, pattern and fire — the qualities that define value in the world's rarest opal. Buy purely to collect, or choose your stone and we'll design and craft the setting around it. Browse the loose stones below, see finished black opal jewellery, or start a custom piece with us in Adelaide.
