Natural Australian Opals Set in .925 Sterling Silver
Australia produces over 90% of the world's precious opal supply, with major deposits in Lightning Ridge, Coober Pedy, and Queensland's boulder opal fields. Lightning Ridge black opals display dark body tones that intensify their color flashes. Coober Pedy white and crystal opals offer translucent bases with broad spectral patterns. Queensland boulder opals form naturally attached to their ironstone host rock, creating organic shapes with rich color concentration. Our sterling silver settings protect each stone while allowing light to enter from multiple angles. This matters because opal's play-of-color depends on light diffraction through silica spheres within the gem. Bezel settings offer security for softer stones, while prong settings maximize light exposure for opals with strong fire. Every pendant ships with free US delivery and arrives ready to wear on your preferred chain.How do I care for an Australian opal pendant?
Store your opal pendant away from direct heat and low humidity. Opals contain 5–10% water content, so avoid prolonged exposure to dry conditions. Clean with a soft damp cloth rather than ultrasonic cleaners or steam.
What causes the colors in Australian opals?
Play-of-color occurs when light passes through microscopic silica spheres arranged in a grid pattern within the stone. Sphere size determines which colors appear—larger spheres produce red flashes, smaller ones create blue and green.
Which Australian opal type is most valuable?
Black opals from Lightning Ridge command the highest prices due to their dark body tone, which makes spectral colors appear more intense. Boulder opals and white opals offer strong play-of-color at lower price points.
