Calcite on Amethyst – Artigas, Uruguay
 
Amethyst in probably the best color and calcite in flawless quality creates this highly aesthetic specimen. The lustrous and transparent amethyst shows the coveted deep purple color that can only be found in a few places in the world. The sharp-edged calcites have a wonderful transparency and are partly covered with highly lustrous second-generation crystals. 
A wonderful, decorative specimen from South America.
