Sterling Silver earrings, featuring Natural Boulder Opals from Australia, stamped with the distinguished 925 mark. Classified as Natural Opal Type 2, these opals naturally attach to a host rock with a unique chemical composition. Genuine Natural Australian Boulder Opals, composed of SiO2nH2O silica concretions, exhibit a rare beauty found exclusively in select regions of Queensland, Australia. Their scarcity and reported annual appreciation of up to 15% contribute to their allure. The pendant is not only a testament to nature's artistry but is also certified free of artificial coloring or dyes. Rest assured, all our Australian Opal Cutters Jewellery and Loose Opal items are backed by an international warranty. Customize your opulent piece by conveying any desired modifications, changes, or specific color preferences during checkout. For a truly personalized touch, explore the option to change or upgrade your opal or alter the entire design, available upon request and at an additional charge. Keep in mind, the enchanting play of colors in opals may make the online representation a delightful but elusive preview, as opals possess a dynamic vibrancy challenging to capture on camera.
