Emerald (Unusually Large Gem Crystal). Cosquez Mine, Boyaca Department, Colombia
This Beryl-Emerald is over 460 carats or nearly 100 grams in mass. Few natural emerald crystals reach this size and attain such uniform intensity of color. The crystal has large gemmy regions that could cut stones, and is itself translucent to transparent around the edges and well into the depths of the crystal. The termination is complete, though it shows some small natural wear, considered acceptable in a gemstone crystal of this magnitude. It shows perfect hexagonal form, typical of smaller emeralds but rarely seen in crystals of large size.
The piece was formerly in the well known collection of Martin Zinn III of Denver, Colorado. It sold in 2003, and since then resides in a private gem crystal collection. This exceedingly large emerald crystal is a treasure worthy of a coronation sceptre, and the size to be seen from across the room. It is a major gemstone crystal and among the largest stones to come this locality.

Size: 460 carats.
A custom lucite base for display is included.
Estimated Value $90,000 - 100,000.
