Todas las subastas / Etnográfica / Colombian Trapiche Emerald - The Rarest and Most...
This specimen is a very rare section of Trapiche emerald, one of the most fascinating and sought-after structures in the entire gemmological world. From the historic mines of Colombia, it is characterized by its six black rays radiating from the center like the spokes of a wheel or the petals of a stylized flower: a unique natural phenomenon, impossible to replicate artificially with the complexity and finesse of the original veining. Trapiche emeralds form inside hydrothermal deposits rich in carbonate and black shales. During crystal growth, the presence of carbon inclusions interferes with the gem’s hexagonal crystallization. This process causes a “separation” of growth into six distinct sectors, divided by very thin dark “barriers” composed of shale residues. The result is an astonishing structure, the compact black center, rich in natural carbon. Six translucent green arms of pure emerald radiate outward following the hexagonal symmetry of the crystal. Dark separation lines, marks of layering and natural interference in mineral growth. Extremely Rare - Colombian Emerald Trapiche Gem Quality AAA Colombian emerald Trapiche.
