This 3.54ct Natural Black Opal from Lightning Ridge, Australia is a mesmerizing oval shaped gemstone featuring vibrant blue and green fire across a black base tone. Bursts of neon aqua and streaks of violet create a cosmic shimmer, while rare hints of red ignite at certain angles, adding intensity and dimension to the stone's character.
The opal's natural solid body and carefully polished surface enhance subtly revealing a unique honeycomb texture under lighting. Though potch lines are present internally, they are not visible to the naked eye, preserving a clean, uninterrupted look on the face of the stone. With its durable 3.5mm thickness and well-balanced 14.9x10.3mm dimensions, it is perfect for a high end custom setting, whether a statement ring or luxurious pendant.
Collectors and designers will appreciate this stone not only for its vivid play of color but also for its authenticity. This black opal is 100% natural and untreated, no doublets, no triplet, just pure black opal, ethically mined beauty from one of the most renowned opal sources on Earth.
Whether you're a collector, artisan jeweler, or someone seeking an heirloom gemstone with rarity and soul, this opal is a true treasure that stands apart.
