Authentic Dioptase Specimen from Congo
Sourced from the Democratic Republic of Congo, this Dioptase specimen showcases the mineral’s striking emerald green coloration and vitreous luster. Each piece is carefully selected to highlight the crystal’s clarity, vibrancy, and naturally formed geometry.
Geological Formation
Dioptase is a rare copper cyclosilicate mineral that forms in the oxidized zones of copper deposits. It typically develops as small, well-defined trigonal crystals within fractures and cavities of limestone or other host rocks. The intense green color is due to copper ions in its crystal structure, and the mineral often occurs alongside malachite, chrysocolla, and other secondary copper minerals. The specific conditions required for Dioptase formation make high-quality specimens particularly rare.
Collector Value
Dioptase is highly prized by mineral collectors for its vivid emerald green color, transparency, and well-formed crystal structure. Specimens from the Congo are especially sought after due to their clarity, vibrant hue, and aesthetic appeal, making them standout pieces in any collection. Its rarity and distinctive appearance enhance its value for display and educational purposes.
Uses & Display
This Dioptase specimen is perfect for collectors, display cases, or educational collections. Its natural formation and intense coloration make it an eye-catching addition to any mineral assemblage.
Care & Handling
Handle gently and avoid harsh chemicals or abrasive surfaces to preserve the crystal’s natural luster and structural integrity.
