Description: A very high quality, gemmy, double terminated, slender aquamarine crystal with a very pale blue colouring. The main termination is beautifully formed (photograph bottom right).
There is a pressure mark in the middle of the shaft, and a very small one towards the upper half. In the lower part of the shaft is something that looks like a flaw, but we're not sure. The crystal has a few very minute nicks.
