This unique mineral specimen features a soft cream to yellowish calcite matrix crossed by a striking vertical band of deep purple amethyst. The rich amethyst crystals run naturally through the center of the piece, creating a beautiful contrast against the lighter stone that surrounds them.

The difference in color and texture between the smooth calcite and the sparkling amethyst makes this piece especially eye-catching. Formed naturally over time, it showcases the fascinating way different minerals grow together within the earth. A wonderful addition to any mineral collection or natural stone display.
