AUSSIE AMETHYST CRYSTAL
A great Aussie Amethyst Crystal. Good natural point and some iron staining around the base of crystal. Just as it was when it came out of the ground. Australian Amethyst is not all that common, and many people do like to have a piece from here. This piece has a great termination and fits well in the hand. The Purple is so dark it appears black on a cloudy day. This specimen was difficult to photograph. One pic is backlit with a torch, other pics taken out doors on cloudy and bright sun days. There are some interesting internal zoning patterns also visible in the photos.
