Analyse Opal Diamond Factory de la part de marché pour juillet 2026

"Established in 1974, Opal Diamond Factory is Adelaide’s oldest and largest opal, diamond and coloured gem specialist. Our collection of South Australian crystal and white opals, Queensland boulder opals and famous Lightning Ridge black opals is the most extensive in Australia. Amid the hot, red dust of Coober Pedy in South Australia’s far north, opal pioneer John Ryneš and son Mike Saj-Ryneš discovered a love for Australia’s national gemstone. At the Opal Diamond Factory, the Ryneš family crafts jewellery, including bespoke pieces, from opals, ethically-sourced GIA certified diamonds and other precious stones. Collaborating with our customers is at the heart of what we do."
