This 3.64ct Natural Dark Opal teardrop from Lightning Ridge is a dazzling celebration of light and color. The surface is alive with vivid flashes of red, blue, green, yellow, and lavender, arranged in a radiant patchwork that evokes a mosaic of pastel flames. Its color play is reminiscent of a metallic pastel rainbow aurora, and the gem seems to glow with an internal light that recalls the shimmer of a unicorn’s mythical rainbow trail.
The opal's symmetrical teardrop cut makes it a premium choice for pendant designs or elegant high-end rings. Its medium dome and fine polish ensure strong light reflection, adding brilliance and dimension from every viewing angle. Whether viewed in daylight or under lamplight, this stone stuns with a lively energy and a dreamy spectrum.
More than just visual beauty, this Australian dark opal embodies symbolism as the October birthstone and carries meanings of creativity, transformation, and rarity. It is a captivating gemstone that offers designers a unique artistic palette and collectors a truly magical addition to their archive.
Whether you're creating a bespoke engagement piece or expanding a rare gemstone collection, this unicorn rainbow fire opal is unforgettable.
