Australian Opal Jewelry  

Natural Australian Opals Set in Sterling Silver

Australian opals form over millions of years as silica-rich water seeps into rock crevices and deposits microscopic spheres that diffract light. The resulting play-of-color depends on sphere size and arrangement. Black opals from Lightning Ridge show color against a dark body tone and command the highest values. White opals from Coober Pedy display color on a lighter base. Boulder opals from Queensland remain attached to their ironstone host rock, creating natural patterns. Opal measures 5.5 to 6.5 on the Mohs hardness scale. This makes it softer than quartz, so opal jewelry benefits from protective settings and mindful wear. Remove opal rings before heavy work. Store pieces separately to prevent scratches. Avoid ultrasonic cleaners and harsh chemicals. SilverRush Style has offered natural stone jewelry since 2005. Every opal in this collection is genuine, not synthetic or lab-created. Sterling silver settings provide durable, hypoallergenic frames for these Australian stones.
