Though it appears a bit rough in places, the anomalies you see on this fine aquamarine crystal are all natural: the modifications along the edge of the top termination, the euhedral contact in the side where another crystal grew against it, etc. It is even DOUBLY-TERMINATED, with a rougher termination on one end and a smooth, glassy one on top. Very gemmy through most of its length. Weighs 27 grams.
