Rare Dioptase XX Specimen from the Republic of Congo – This exceptional mineral specimen is distinguished by its pronounced, dark green to turquoise dioptase crystals with an angular growth pattern. Dioptase is a rare copper silicate mineral with a characteristic emerald-green color, primarily captivating collectors and mineral enthusiasts. Its compact size of 15×14×8 mm and weight of only 1.5 g make this specimen a valuable collector's item.
The mineral is characterized by its vitreous luster and intense green color, which results from its high copper content. With a Mohs hardness of 5, dioptase is significantly softer than emerald and therefore primarily suitable as a collector's item. Its perfect cleavage and prismatic crystal structures make each specimen a unique geological find.
