Zarah operates directly within Colombia’s emerald trade, with a presence in Bogotá and western Boyacá, including the Muzo and Maripí mining region. We work independently across different sources and maintain direct relationships with miners, mine owners and other participants within the local trade.

Zarah primarily supplies cut and polished Colombian emeralds, including single stones, matched pairs, calibrated stones and layouts. We also have the capability to supply rough Colombian emerald material for specialist requirements and trade clients, subject to availability and specification.
