Large Deep Purple Amethyst Geode – 30.75 lb | Natural Uruguayan Crystal

A Mineralogically Rare Deep Purple Amethyst Geode from Artigas, Uruguay

This 30.75 lb deep purple amethyst geode from Artigas, Uruguay is among the most mineralogically active specimens in this collection. The primary crystal face is covered in a dense bed of small, tightly packed amethyst points with a deep purple-to-near-black color and intense metallic shimmer — the signature of high-iron Uruguayan material formed under exceptional pressure.

Multiple Mineral Generations — Secondary Lavender Druzy Growth Atop White Quartz

Embedded within the crystal surface is a secondary formation: a fresh growth of soft lavender druzy amethyst has developed directly atop the white quartz zone, alongside a natural quartz cavity with its own distinct crystal points. This layered mineral sequence — primary deep purple amethyst, white quartz, secondary lavender druzy — is a rare geological record of multiple growth phases within a single specimen.

The wide, low-profile form gives this piece an unusually strong horizontal presence, making it ideal for large shelves, console tables, or floor displays where height is not the primary consideration. Flat-cut base, stand-free. One of a kind.
