Uruguayan Amethyst Cathedral with Calcite & Goethite

Deep violet druzy lines this Uruguayan amethyst cathedral, framed by natural agate banding and dark basalt exterior. Clear calcite crystals form inside the cavity, with visible goethite inclusions adding contrast and mineral complexity.

Uruguayan amethyst is known for tighter crystal points and darker, more saturated purple tone than Brazilian material. The sparkle is fine, dense, and high quality.
