olombian emeralds are mined in the Eastern Cordillera of Boyacá, Colombia—primarily at the Muzo, Coscuez, and Chivor mines—and have been prized since pre-Columbian times, when they were traded by the Muisca people for ritual use and adornment. Formed in hydrothermal veins cutting sedimentary rocks, these beryl gems owe their vivid, perfectly saturated green to chromium and vanadium trace elements, and they often exhibit exceptional clarity compared to other sources. Today, Colombia supplies over half of the world’s emerald production, and its stones remain the benchmark for color and quality among collectors and jewelers alike. Because of their high value as cut stones, few specimens reach the collector market. This particular specimen features a nice spray of vibrant green emerald crystals (to about 4-4.5 cm) with some associated pyrite on matrix. Not all of the emerald crystals are terminated, but it remains an excellent display specimen.
