A very large plate of lustrous, large deep-purple Amethyst crystals with a cluster of highly translucent, colorless, intergrown parallel Calcite “nailhead spar” crystals perfectly centered and emanating from the middle of the Amethyst. It is incredible! Amazing color, luster, symmetry and crystal formation. In excellent condition.
