Beryl from Muzo Mine, Colombia

from Muzo Mine means emerald in its most storied Colombian expression: saturated green Be3Al2(Si6O18), colored chiefly by chromium and vanadium, set against white calcite, black shale, pyrite, and, more rarely, quartz. To collectors, the finest Muzo pieces are not simply “emerald specimens”; they are the reference point by which many other emerald localities are judged. The best examples combine a vivid, slightly velvety green with a glassy luster, sharply hexagonal prism form, and a matrix that tells the whole geological story at a glance: green crystal, white carbonate vein, dark carbonaceous host rock, and metallic pyrite.
