This page gathers the stones in our collection whose origin is recorded as Colombia. At present that means a single variety: the Colombian emerald, the green gem form of the mineral beryl, coloured principally by traces of chromium and vanadium within its crystal structure.
Colombia has been associated with emerald for centuries, and the deposits of its eastern cordillera differ geologically from most others: the crystals form in calcite veins within black shales rather than in the mica schists that host many emeralds elsewhere. Gemmologically, this frequently expresses itself as a slightly warmer, more saturated green and a characteristic set of internal inclusions.
When choosing between Colombian emeralds, weigh colour first — depth of green, and whether the tone leans bluish or warm — then consider clarity in the context of the variety. Emerald is a type III gemstone, meaning inclusions and fissures are expected rather than exceptional, and the aim is a stone whose inclusions do not compromise its brilliance or durability. Cut quality, proportion and any disclosed treatment on the individual listing complete the picture.
