enchanting beauty of our Natural Australian Opal Triplet Earrings, crafted in Sterling Silver and stamped with the mark of authenticity, 925. These earrings feature exquisite Triplet Opals, classified as Genuine Natural Australian Opal Type 3, creating a harmonious blend of elegance and sophistication. Triplet Opal is a fascinating assembly that begins with Gem Light Opal, a hydrated amorphous form of silica SiO2nH2O, where spheres of silicon dioxide molecules are meticulously arranged in regular, closely packed planes. This mesmerizing gem is backed by Australian Black Opal potch and crowned with a cabochon layer of silica quartz, ensuring a seamless composition. The three layers share the same coefficient of thermal expansion, offering a lifetime guarantee against delamination.
