0.69 Ct. Multi Color Semi-Black Opal from Australia

This translucent 0.69 carat freeform Semi Black Opal from Australia measures 10.44 x 6.09 x 1.56 mm, and it presents a polished cut with an eye clean clarity grade, evaluated at eye level, intense color intensity, and an excellent polish. Compared to many mass market opals that are small, heavily treated, or uniform in shape, this opal stands out with a vibrant multi color play that rivals higher carat pieces, while remaining compact enough for finely detailed custom work. Because it is a Semi Black Opal, the depth of color and contrast of the fire are richer than typical white opals, yet the translucency allows light to penetrate and reveal internal flashes of red, orange, green, and blue, giving designers a wider tonal palette to work with. The fact that there has been no enhancement adds real value, making this stone a rare find for clients who want natural beauty and honest sourcing in their bespoke pieces.

For custom jewelry, the freeform shape and the specific dimensions of 10.44 x 6.09 x 1.56 mm make this gem exceptionally versatile, because it can be set as a small statement pendant, a unique ring center for a slender band, an eye catching inlay, or an accent stone flanking a larger gem. Compared to standardized round or oval cabochons, the freeform silhouette allows jewelers to design settings that complement the stone rather than forcing the stone to conform to a common shape, and this often results in more original, couture style pieces. The polished cut and excellent surface finish reduce the need for additional labor, which keeps production costs competitive while preserving the opal integrity. At 0.69 carat, the stone strikes an ideal balance between presence and practicality, offering enough size to show lively play of color, while remaining suitable for delicate and comfortable wearable designs. From a value perspective, this stone competes strongly with similar offerings on the market because of its eye clean clarity, intense color, natural origin, and no enhancement status. The Natural Gemstone Company is proud to offer this Australian Semi Black Opal to designers and collectors who want a unique, high quality gem that transforms custom creations into heirloom pieces.
