This 5.11ct solid Australian black opal from Lightning Ridge is a natural, untreated gemstone mined in New South Wales, Australia. Expertly cut and well polished in an elegant teardrop cabochon shape, this opal measures 17.3 × 10.6 × 4.3 mm and features a dark black body tone that provides the perfect canvas for its extraordinary color display.

Intense electric blue fire dominates the surface with captivating violet undertones that create a mesmerizing depth of color. The play of color shifts dramatically with movement and light angles, revealing brilliant flashes that range from cobalt blue to deep purple. The broad flash pattern creates exceptional brilliance across the entire teardrop surface, making this a truly museum quality specimen that showcases Lightning Ridge's legendary reputation for the world's finest black opals.

The elegant teardrop cabochon shape makes this black opal ideal for sophisticated jewelry designs that demand attention. Jewelry designers appreciate the teardrop form for statement pendants where the distinctive shape becomes a dramatic focal point, or custom rings that showcase the stone's impressive presence. The 4.3 mm profile provides excellent dome height for bezel settings in modern designs or prong mountings for classic creations. This gemstone works beautifully in platinum, gold, or sterling silver settings that enhance the electric blue fire, and is perfectly sized for engagement rings, cocktail rings, or elegant pendant necklaces that make unforgettable statements.

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 substantial 5.11 carat weight and intense electric blue 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 investment grade 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 teardrop shape combined with the intense electric blue fire and dark body tone make this a truly exceptional gemstone that represents the pinnacle of Australian opal quality.

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.
