Amethyst and Calcite Geode

A bold and bright burst of purple amethyst crystals with a beautiful rainbow-included calcite crystal. This stunner comes from the volcanic rock deposits of Uruguay. Amethyst is a purple variety of quartz which forms within basalt pockets. The calcite crystal formed as a secondary mineralization and crystallized with a pretty rainbow inside (seen when tilted in the light).

Approx. 5.25" L x 2" W x 3.75" H
