This specimen is a fine miniature featuring good quality, sharp, gemmy, lustrous, prismatic, purple color "reverse" scepter crystals of Amethyst measuring up to 1.6 cm sitting atop grey modified rhombohedra of Calcite on matrix. This piece is remarkable for Bolivia as it features a type of crystallization that is virtually unheard of from Bolivia. This is one of the nicer pieces from the find for quality, aesthetics and overall appeal.
