1.90 Ct. Multi Color Black Opal (Dark Opal) from Australia

This listing describes one natural Black Opal, Dark Opal, weighing 1.90 carats, with a fancy shape and tablet cutting style, supplied by The Natural Gemstone Company. The gem presents as opaque with intense color intensity and an excellent polish, exhibiting broad multi color play across its surface. Dimensions are 11.72 x 7.35 x 2.60 mm, which reflect a low profile tablet form that emphasizes surface color rather than depth. The cutting style is tablet, which provides a relatively flat crown and gentle bevels at the edges to preserve maximum color play while maintaining a compact profile. There has been no enhancement to this stone, and its documented origin is Australia, a source renowned for high quality Black Opal material. Color distribution is multi chromatic, with vivid flashes of green, red, and blue set against the darker body tone that defines the Black Opal category, and the overall finish displays a uniform polish that aids visual clarity and consistency under a variety of lighting conditions.

The proportions and shape of this 1.90 carat tablet opal make it particularly well suited to bespoke jewelry applications, where specific orientation and design lines are important. The 11.72 mm maximum length and 7.35 mm width place the stone in a size range that provides a visible focal point without requiring an oversized mounting, and the 2.60 mm thickness allows for secure bezel settings or low profile prong styles while keeping the finished piece comfortable for everyday wear. The tablet cut and flat surface are advantageous for settings that require stable, flush mounts or that incorporate the stone into inlay work, and the even polish reduces the need for extreme elevation in the setting to achieve optimal light return. Designers working with mixed metal palettes will find the dark body tone and intense color play complementary to yellow gold, rose gold, and platinum, enabling contrasting treatments that enhance the opal color rather than compete with it. The fancy shape introduces a geometric element that can serve as a central motif in rings, pendants, cufflinks, and brooches, or as an accent in asymmetrical and modern layouts where unique outlines are desirable.

From a practical standpoint, the stone presents clear parameters for production and conservation which facilitate its incorporation into custom pieces. The absence of enhancements confirms that the material will respond to standard opal care protocols and that its natural body tone and color play are intrinsic properties of the specimen. The tablet cut minimizes internal stress by maximizing the face area and limiting excessive thinning, which can be an important consideration for lapidary handling during bezel seat preparation or when setting adjacent stones. The 1.90 carat weight provides a balance between presence and manageability, offering sufficient mass for secure mounting hardware while avoiding the bulk that can complicate ergonomic design.
