This is a jaw-dropping cluster of sparkling dioptase crystals that was collected from the N'tola Mine in the Republic of the Congo. This mine has been closed since 2019, so this material is old stock. This large specimen measures 9.1" wide and the dioptase is a lustrous, emerald-green color. Golden mimetite crystals can be found along one edge of the matrix.

About Dioptase

Dioptase is a showstopper in the mineral world—an electrifying copper silicate known for its mesmerizing, emerald-green color that seems to glow from within. Its vivid hues rival even the finest emeralds, but it’s the crystal clarity and intense brilliance that make collectors’ hearts race. Found in arid, copper-rich environments like the deserts of Namibia and Kazakhstan, dioptase forms stunning prismatic crystals that sparkle like tiny green beacons against contrasting matrix rock. While too soft for most jewelry, it’s a favorite among mineral collectors and museums for its sheer visual impact. Dioptase isn’t just a mineral—it’s nature’s answer to green fire in crystal form.
