Gemmy “Electric” Dioptase Crystal Cluster – 30mm

Description

This 30mm specimen is exceptionally “gemmy,” featuring high transparency in the crystal terminations that allows light to penetrate deep into the cluster.

Gemmy “Electric” Dioptase Crystal Cluster – 30mm

Locality: Republic of the Congo (DRC)

Dimensions: 30 mm x 18 mm x 12 mm

Mineralogical Highlights

This 30mm specimen is a standout for its clarity and internal light play. While many dioptase clusters are opaque, this piece features several larger, sharp rhombohedral crystals with translucent edges that glow with a neon teal-green when backlit.

• Crystal Habit: Notable for its sharp, well-defined terminations. The crystals are predominantly blocky rather than drusy, providing a clean, geometric aesthetic.

• Luster: High vitreous luster. The reflective crystal faces are particularly smooth, resulting in sharp, pinpoint light returns that give the piece a “jewel-like” quality.

• Color Saturation: Exhibits a vivid, high-saturation emerald-green. The presence of the thin, light-colored matrix at the base provides a perfect contrast that makes the green appear even more intense.

• Transparency: The crystals possess a “gemmy” quality, allowing for significant depth and internal reflections that are rare in larger, more massive clusters.

Technical Summary

• Mineral: Dioptase ($CuSiO_{2}(OH)_{2}$)

• Hardness: 5 (Mohs Scale)

• Crystal System: Trigonal / Rhombohedral

• Condition: Natural and pristine; featuring excellent crystal faces with no visible damage.
