Dioptase, Tantara Mine, Shinkolobwe, Kambove Territory, Haut-Katanga, DR Congo
An architecturally complex Tantara Dioptase, presenting large, gemmy, deep emerald-green crystals with striated to glassy faces and intricate geometric patterns. The reflections and internal refraction are striking. This is a nice, small cabinet piece presenting some peripheral separation features. Sourced from a forty-year-old collection.
