1.89 Ct. Black Opal from Australia

This listing describes one Black Opal from Australia, weighing 1.89 carat, with a trillion shape and dimensions of 13.63 x 8.79 x 2.67 mm. The stone is opaque and cut in a tablet style, producing a broad, low profile surface that showcases intense play of color. The tablet cut and excellent polish deliver strong, even flashes of green, blue, and orange across the surface, while the dark body tone characteristic of Black Opal enhances contrast and depth. No enhancement has been applied, so the color and surface finish are natural attributes of the material. These technical details, including the exact proportions and the 2.67 mm thickness, allow precise evaluation for setting and design planning.

The tablet cut and trillion outline make this opal particularly versatile for a range of jewelry configurations. Its low profile and even girdle are well suited to bezel settings, which provide secure protection and a clean visual frame that complements the opals color. The triangular form lends itself to asymmetrical ring designs, tapered pendant mounts, and drop earring layouts where orientation can be adjusted to highlight specific color flashes. For a more contemporary aesthetic, a fine channel or inlay application preserves the tablet surface while integrating the stone into a band or cuff. When a focal statement is desired, a diamond halo or small accent stones can be set around the opal to increase perceived size and enhance color contrast, with warm metals such as yellow or rose gold emphasizing orange and green tones, and white metals such as white gold or platinum providing a crisp, modern backdrop. The Natural Gemstone Company recommends custom seats that align with the stones dimensions to avoid stress at the edges and to maintain a secure fit.

Practical considerations for fabrication and long term wear should guide final setting choices. The tablet cut and 2.67 mm thickness create a shallow pavilion, so jewelers should prepare a correspondingly shallow seat and consider a bezel with a slight lip for impact protection. Open back bezels can be used to increase light interaction and color vibrancy, while closed back bezels will deepen the body tone and accentuate the opals dark background. Because this Black Opal is untreated and naturally formed, care during fabrication is important, with soldering and post setting work conducted in a way that avoids direct heat stress. For daily wear pieces, especially rings, protective mounting options are preferred to reduce the risk of chipping, and for delicate designs The Natural Gemstone Company can supply precise measured drawings and photographs to facilitate accurate setting. We are available to consult on metal choice, complementary stones, and design adaptations to ensure the finished piece respects the gemological properties of this opal and achieves the intended aesthetic and wearability.
