2.64 Ct. Semi-Black Opal from Australia

This beautiful translucent Semi-Black Opal from The Natural Gemstone Company is a striking example of Australian opal craftsmanship, weighing 2.64 carats and cut into a classic oval shape for timeless versatility. The stone measures 12.44 by 9.21 by 3.48 millimeters, making it an elegant size for rings, pendants, or statement earrings. The tablet cut enhances its surface lustre, producing broad, vibrant flashes of color across a smooth, domed face, while the back remains subtly layered to preserve depth and light interaction. Clarity is graded as eye clean when evaluated at eye level, so the face presents an open, pleasing field without visible inclusions to distract from its play of color. Color intensity is intense, with saturated flashes that jump from green to blue to fiery orange and red as the angle of light shifts, offering a lively and dynamic display that is typical of the finest semi black opal material. The polish is excellent, providing a glasslike finish that amplifies the stone's color and translucency. Importantly, this opal has received no enhancement, and its natural origin in Australia speaks to its quality and the long tradition of Australian opal mining.

Visually this multi color opal offers a rare balance between dark body tone and vibrant play of color, hence its designation as a semi black opal, which often yields more dramatic color contrast than lighter white opals while maintaining a luminous, translucent character. The tablet cut creates big, painterly flashes that read like patches of color on a palimpsest, and the way the hues move makes this a living jewel that rewards movement and changing light. For settings, consider a low bezel to protect the edges and preserve the clean tablet surface, or a halo design to accentuate the central color fields and add brilliance from surrounding accent stones. Because of its 2.64 carat weight and 12.44 by 9.21 millimeter dimensions, it sits beautifully on the finger for everyday wear when properly set and fitted, and it translates into an eye catching pendant when mounted vertically to showcase the full spectrum. This opal is ideal for clients seeking a gemstone that is at once sophisticated and expressive, a piece that reads as both gemstone art and wearable treasure. As a semi black opal of Australian origin with no enhancements, it carries intrinsic appeal for collectors who value natural color, purity, and provenance.

Caring for this opal is straightforward, and as responsible gem professionals we recommend simple precautions to keep its beauty intact. Avoid sudden temperature changes, harsh household chemicals, and ultrasonic cleaners, all of which can stress the structure of opal. Clean gently with a soft cloth and mild soapy water, and dry thoroughly before storing in a padded compartment to reduce the risk of scratching or chipping. For long term security and to enhance everyday durability, a protected setting such as a bezel or partial bezel is an excellent choice.
