This specimen was a pleasant surprise. When purchased, was with its natural cover and the prospector put cement in the base (to stand up, trying to take advantage of its forms). Was laborious get the cement off and when the piece was properly washed surprised us with its beauty and form. Simply the best amethyst flower that we found.
