This 2.7ct solid Australian black opal from Lightning Ridge is a natural, untreated gemstone mined in New South Wales, Australia. Expertly cut and well polished in a distinctive freeform cabochon shape, this opal measures 15 × 11.3 × 3 mm and features a deep black body tone that provides the perfect canvas for its extraordinary rolling fire display.

Bright green and blue rolling fire flashes across the surface, revealing brilliant play of color in a stunning broad flash pattern. The freeform shape showcases vivid color waves that roll and move across the stone, creating a mesmerizing display that combines emerald green with deep sapphire blue. The rolling fire pattern creates exceptional brilliance with dynamic movement across the entire organic surface, making this a truly distinctive specimen that showcases Lightning Ridge's world renowned quality for producing the finest black opals.

The unique freeform shape makes this black opal ideal for artistic jewelry designs that celebrate natural forms. Jewelry designers appreciate the organic form for statement pendants where the distinctive shape becomes the focal point, or custom rings that showcase the stone's unique character. The 3 mm profile provides excellent proportions for bezel settings in modern designs or specialty prong mountings for sculptural creations. This gemstone works beautifully in platinum, gold, or sterling silver settings that enhance the green and blue rolling fire, and is perfectly sized for statement rings, artistic pendants, or elegant necklaces that showcase contemporary aesthetics.

This is a 100% natural solid black opal, never treated and not a doublet or triplet, making it highly desirable for collectors and fine jewelry designers. The distinctive freeform shape and bright rolling color play make it ideal for use as a ring stone, pendant centerpiece, or bespoke statement jewelry, while also appealing to serious opal collectors seeking unique Lightning Ridge material with exceptional fire and premium body tone.

As Australia's national gemstone and the October birthstone, this Lightning Ridge black opal carries both symbolic and collectible value. Black opals from Lightning Ridge continue to appreciate as the mines yield fewer world class specimens each year. The freeform shape combined with the rolling green and blue fire make this a truly exceptional gemstone for contemporary jewelry enthusiasts and collectors.

This stunning opal will arrive securely packaged in an Opal Galaxy gift box, making it ready for safe storage, jewelry setting, or presentation as a collector gemstone.
