Dioptase on Matrix, Morocco

Discover the enchanting beauty of Dioptase, a rare green crystal specimen known for its vibrant color and brilliance. Sourced from the rich mineral deposits of Morocco, this exquisite copper silicate mineral (chemical formula CuSiO₃·H₂O) crystallizes in the trigonal system, forming sharp, well-defined hexagonal prisms. With a Mohs hardness of 5, Dioptase exhibits a vitreous to sub-adamantine luster that enhances its vivid emerald-green hue.

This specimen features intense, translucent to transparent crystals contrasting strikingly against a red-brown matrix, typical of Moroccan localities such as the Bou Azzer mining district. The sharply terminated crystals display excellent clarity and depth of color, making it a valuable piece for mineral enthusiasts and collectors seeking specimens with both aesthetic appeal and mineralogical significance.

Dioptase’s rarity and distinctive coloration contribute to its desirability, especially in well-preserved forms with intact crystal faces. This specimen’s display quality makes it suitable for both private collections and educational purposes.

Due to its moderate hardness and crystal delicacy, handle the specimen with care, avoiding exposure to excessive moisture or harsh chemicals to preserve its luster and structural integrity over time.
