Opal Diamond Factory



“Our family has been crafting the finest pieces from opals and diamonds for over 45 years. But that is nothing compared to the six million years it takes to create an opal” Opal Diamond Factory

For over 45 yeas Opal Diamond Factory has been Adelaide’s oldest and largest opal diamond specialists. Established in 1974 by opal pioneer John Ryneš, we are a second-generation family-owned manufacturing jeweller and opal cutter.

Located in the heart of city, King William Street, Adelaide, South Australia, in the iconic Beehive Corner.

Specialising in custom made jewellery, we love working with our clients to create that special piece they have been looking for. Whether you’re wanting to create a bespoke engagement ring or looking to remodel an old treasure, we guarantee a tailored and original experience.

“Being based in Adelaide and having formed strong relationships with the miners over the years, has allowed us to create the most amazing pieces for our clients. Being a true family business allows us to maintain the highest standards in customer service and manufacturing. For over 45 years we have been creating the most exquisite pieces. There is a real person behind each piece.” Mike Saj-Rynes
