3.91 Ct. Multi Color Cabochon Black Opal (Dark Opal) from Australia

From the ancient silica beds of Australia this AGL certified Black Opal traveled from rugged outcrops to the careful hands of our lapidaries, carrying a history written in geological time. Unearthed in a region known for producing dark opal, this multi color gemstone weighs 3.91 carat, and is fashioned into an elegant oval shape cabochon measuring 13.28 by 8.91 by 5.25 mm. Its surface has been polished to an excellent finish, and because it is free of any enhancement, the intense play of color you see is wholly natural. At The Natural Gemstone Company we enjoy telling the story of a gem from rough to radiant, and this opal is a vivid chapter, showing flashes of green, blue, and violet across a dark ground that intensifies every hue.

The stone is graded very slightly included evaluated at eye level, and those tiny internal signatures are part of what makes this black opal uniquely identifiable. Rather than imperfections, the small inclusions appear as fine silica patterns and delicate potch areas that sit beneath the surface, they interact with light to create depth and character and they act as a fingerprint that confirms natural origin. To a gemologist these inclusions are reassuring signs of authenticity, and to a wearer they add texture to a living canvas of color, catching light differently with each movement. The cabochon cut amplifies the opal's play of color while preserving these internal features, making this gem ideal as a centerpiece for a ring or pendant where its flashes can be enjoyed up close. As a salesperson familiar with gemstones I can say that a dark opal like this offers both rarity and personality, a responsibly sourced Australian Black Opal that is AGL certified and ready for a custom setting.
