A good ring stone is more than a beautiful opal — it needs proportions, dome and durability suited to daily wear. The stones below are singles cut in the shapes and profiles that jewellers ask us for when they are building rings.
Each stone page shows exact millimetre dimensions, carat weight, body tone and brightness, with video — so you (or your jeweller) can plan the setting before the stone arrives. Our opal buying guide covers what to look for.
