Australia’s oldest and largest manufacturer of custom handmade opal and diamond jewellery

Established in 1974 by opal industry pioneer John Ryneš, we are a second-generation family-owned jeweller specialising in opals, diamonds, pearls and coloured stones.

Our collections and exquisite custom jewellery are handmade right in front of you, in our on-site workshop. You are very welcome in our King William Street shop; please join us on a personalised tour of our rare opal and certified diamond collections.
