0.49 Ct. Semi-Black Opal from Australia

This translucent semi black opal from Australia is a remarkable example of natural beauty and rarity, and it stands out clearly when compared to the more common white opals and to treated specimens offered elsewhere. We present one freeform shape multi color opal weighing 0.49 carat, with precise dimensions of 8.28 x 5.99 x 1.88 mm. The stone displays intense color intensity and a lively play of green and blue flashes that appear across the surface as the light moves. The clarity has been evaluated as eye clean at eye level, which means the gem presents a clean field to the naked eye without any inclusions that would distract from its color or brilliance. Unlike assembled stones such as opal doublets and triplets that can obscure natural depth and reduce longevity, this opal is solid and untreated, making it a purer and longer lasting choice. When customers compare this piece to other market offerings, the semi black body tone delivers more optical depth than a white opal, while remaining more affordable than a full black opal, translating to exceptional value for collectors and designers alike.

Quality matters in opals, and this gem excels in every practical category that affects both beauty and long term satisfaction. The polish is excellent, offering a smooth reflective surface that maximizes the play of color and gives a pleasant feel when set in jewelry. The stone has received no enhancement, which means its natural attributes are preserved and predictable over time, a key consideration for those who view gemstones as investments or heirloom pieces. Origin plays a significant role in quality perception, and Australian opals are widely regarded as the benchmark for play of color intensity and structural stability. When set against synthetics or heat treated stones, this Australian semi black opal retains the advantages of natural formation, namely unique internal patterns and a depth to color that lab grown alternatives cannot mimic. Buyers who seek authenticity and integrity will find this offering from The Natural Gemstone Company superior in terms of provenance and treatment disclosure.

The freeform shape of this 0.49 carat opal adds to its desirability for modern and bespoke jewelry design, because artisans can accentuate the stone rather than forcing the gem into a standard shape that may diminish its character. Freeform cuts are particularly valuable when the opal displays irregular but intense color patches, as is the case with this piece, allowing the cutter to preserve the most striking play of color. At just under half a carat, the gem is ideally suited for an elegant ring, a refined pendant, or as a complementary accent in a pair of artistic earrings. Compared to larger stones that may command premium prices or to very small stones that may lack presence, this size offers the best of both worlds, a wearable scale coupled with noticeable color performance. The semi black background enhances the vibrancy of green and blue flashes in this specimen, creating contrast and movement that many buyers prefer, and at a fraction of the cost of true black opal material.
