This specimen is a great small cabinet size piece consisting of super quality, sharp, gemmy, highly lustrous, prismatic, purple prismatic crystals (one of them is a slight scepter habit) of Amethyst measuring up to 1.5 cm sitting atop white/colorless, modified scalenohedra of Calcite on matrix. This piece is remarkable for Bolivia as it is from an "Alpine-type" locality, and features a type of crystallization that is virtually unheard of from Bolivia. This is one of the best pieces from the find for quality, aesthetics and overall appeal. Ex. Brian Kosnar.
