About Dioptase
Dioptase is a showstopper in the mineral world - a copper silicate known for its mesmerizing emerald-green color. Its vivid hues rival even the finest emeralds, although its crystals lack the equivalent clarity. 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 striking visual impact. It has a chemical formula of Cu₆Si₆O₁₈·6H₂O, alternatively reported as CuSiO₂(OH)₂.
