Amethyst with Calcite
A very large plate of lustrous, large deep-purple Amethyst crystals with two clusters (one large and one smaller) of highly translucent, colorless, intergrown parallel Calcite “nailhead spar” crystals emanating from the center of the plate of Amethyst. It is incredible! Amazing color, luster, symmetry and crystal formation. In excellent condition.
