Australian Triplet Opal Cufflinks, featuring stunning 18x13 mm opals set in 925 Sterling Silver. These cufflinks are not just accessories; they are a testament to the timeless beauty of natural Australian opals. The opals showcased in these cufflinks are of the Triplet Opal variety, classified as Genuine Natural Australian Gem Crystal Opal of Type 3. This opal type is a captivating assembly of hydrated amorphous silica SiO2AnH2O, with spheres of silicon dioxide molecules arranged in regular, closely packed planes. The opals are backed by Australian Black Opal and capped with a cabochon layer of silica quartz. Importantly, the three layers share the same coefficient of thermal expansion, ensuring durability and a lifetime guarantee against delamination.
