This exceptional 78-gram emerald specimen displays vivid green emerald crystals beautifully embedded in a glittering pyrite and shale matrix — a signature association from the Chivor Mine in Colombia’s Boyacá Department. The Chivor locality is renowned among collectors for producing emeralds of exceptional clarity, bluish-green hue, and gemmy translucence, prized for both their beauty and historical significance.

Each crystal in this piece glows with an intense, luminous green tone that stands out against the metallic luster of the pyrite. The contrasting dark shale provides a natural stage that amplifies the color saturation of the emeralds, resulting in a visually captivating tri-tone palette of green, gold, and black.

Measuring approximately 47 × 31 mm, this compact yet commanding piece offers outstanding display aesthetics. It highlights both the geological context of Colombia’s famed emerald deposits and the natural harmony of its mineral assemblage. Pieces like this — featuring gemmy emeralds in situ on pyrite — are becoming increasingly rare in today’s market, especially those that preserve their integrity and luster.

Whether showcased in a mineral cabinet, used for educational study, or simply admired for its natural beauty, this specimen embodies the union of earth’s artistry and scientific value. Its authenticity and provenance from Chivor make it a premium addition to any fine mineral collection.
