Here is a very big and nice amethyst. This one has crystals that is bigger than you will normally see.
The crystals nice and sharp, blank in th the bottom and dark blue in the top. One crystal is cut off, but otherwise damage free except at the bottom of the edges.
I have collected minerals all my life, and this one is a specimen I had in my collection since I was a child, so it is collected in the 1980's or earlier. Unfortunately I don't know the location, but I would believe it is from South America.
