Loose natural black opal cabochon gemstone. This oval cabochon opal displays a dark body color with vibrant flashes of red, blue, green, and yellow play of color visible across the surface. Ethiopian opals are highly valued for their vivid color display and shifting light patterns that change as the stone moves. The smooth cabochon cut enhances the natural optical effects within the stone and allows the play of color to be seen from multiple angles. The oval shape offers excellent coverage and makes the gemstone ideal for a custom ring, pendant, or collector specimen. This gemstone includes a UGL appraisal report confirming the stone details and estimated retail replacement value for insurance purposes.
