This 0.5ct Natural Black Opal from Lightning Ridge, Australia is a radiant example of premium quality in a compact, triangle-cut gemstone. Despite its size, it bursts with intense rainbow fire, flashing vivid hues of red, orange, gold, green, and violet. Each movement reveals a new layer of brilliance, magnified by its dark body tone—a signature trait of solid black opals from this renowned Australian opal region.
The gem is finely polished into a sleek triangle cabochon, offering a modern and geometric look perfect for high-end custom jewelry. Whether you're designing a luxury black opal ring, a one-of-a-kind pendant, or looking for a standout piece to add to your gemstone collection, this natural opal offers fire, rarity, and elegance in equal measure.
Sourced ethically and left untreated, this opal is 100% natural — showcasing the raw, untamed beauty that defines the best Australian opals. Lightning Ridge is known worldwide for producing some of the brightest and most stable opals, and this gemstone is no exception. The shape, fire pattern, and finish make it ideal for small opal ring settings, minimalist high-luxury designs, or collectors looking for investment-grade stones under 1 carat.
As the official October birthstone, this opal also holds symbolic meaning, tied to creativity, clarity, and inner strength. It's a rare and dazzling treasure — small in size, bold in impact, and unmistakably luxurious.
