- Dioptase, Plancheite
- Miniature, 3.3 x 2.0 x 1.8 cm
- Brazzaville (Reneville; Djoue), Brazzaville Department (Reneville Department), Republic of Congo (Brazzaville)
An old-time, showy and excellent combination toenail of deep, emerald-green dioptase crystals nicely accented by pastel blue-green plancheite botryoids from Reneville, Republic of the Congo. This piece was undoubtedly collected in the 1950s and this locality is now extinct. I like the pointed ends, covered with gemmy dioptase crystals. Ex. Jack Halpern Collection #2516.
