About Us


Established in 1974 in the Opal capital of the world, Coober Pedy, and now situated in Adelaide’s iconic Beehive Corner, we are a second generation family owned business and Adelaide’s oldest and largest opal and diamond specialist.

After 40 years in the opal industry we pride ourselves on having Australia’s largest collection and BEST PRICES on South Australian crystal and white opal, Queensland boulder opal and the famous Lightning Ridge black opal.

Our founder John Rynes, is a pioneer within the opal industry and is one of Australia’s most experienced opal cutters. Having trained over 14 apprentices over his career, his knowledge and enthusiasm is recognised within the industry. John’s son Mike Saj–Rynes has since taken ownership of the business and continues to work closely with his father. They both work closely together providing an entertaining and original experience. Following in his footsteps is his son, managing director, Mike Saj-Rynes.

Mike and his team are constantly engaged in building the brand and family tradition that is respectfully known as the Opal Diamond Factory.
