A very rare, doubly terminated, blue-green aquamarine crystal from one of Colombia's great emerald mines - the Chivor Mine. One-half of this glassy, textbook, hexagonal crystal is water-clear, while the other half is translucent. This is older material from the Dick Jones Collection. Very nearly pristine. Weighs 12.22 carats or nearly 2.5 grams.
