Beryl
specimen number:
9711748
location:
Copperbelt Province, Zambia
description: Emerald occurrences in the Copperbelt province of Zambia were first discovered in the Kafubu area in 1928, though significant commercial production did not begin until the 1970s and 1980s; major industrial mines like Kagem remain active today so a closing date does not apply. Geologically, these deposits formed during the Pan-African orogeny when beryllium-rich pegmatites and quartz-tourmaline veins intruded chromium- and vanadium-bearing ultramafic and metabasite host rocks (such as talc-magnetite schists), creating phlogopite reaction zones where emerald crystallization took place.
A loose stacked grouping of deep green translucent semi lustrous beryl crystals, this the variety often called emerald. In great condition.
