This 82-gram emerald specimen comes from the world-famous Chivor Mine in Colombia’s Boyacá Department, one of the most storied sources of gem-quality emeralds on Earth. It features a vibrant blue-green emerald crystal beautifully embedded within a contrasting white calcite and dark shale matrix — a classic mineral association unique to this region.

The emerald displays excellent translucence and a saturated hue that radiates even under natural light. Its prismatic crystal faces reflect subtle flashes of brilliance as you rotate the piece, revealing fine internal zoning typical of true Chivor material. The surrounding calcite forms a sugary white backdrop, while the matte black shale provides dramatic contrast, creating a natural frame that amplifies the emerald’s glow.

Measuring approximately 51 × 35 mm, this specimen offers both aesthetic beauty and geological significance. It exemplifies the hydrothermal mineralization processes that occurred within Colombia’s sedimentary formations — where mineral-rich fluids crystallized emeralds alongside calcite and pyrite within fractures of black shale.

Highly collectible and visually balanced, this piece stands as an authentic representation of Colombia’s emerald heritage, making it ideal for fine mineral displays, curatorial collections, or as a statement piece in any natural-history showcase.
