Rare open Amethyst Geode with very long Amethyst Stalactite Formations from Uruguay

An open Uruguayan amethyst geode with very long amethyst stalactites. The small stalactite columns hang vertically into the cavity from the geode ceiling.

Amethyst stalactites form when quartz columns grow vertically from the geode ceiling during the mineralization phase. Very long stalactites indicate exceptionally stable solution conditions and long growth phases.

Uruguayan amethyst crystallizes in volcanic geodes of the Arapey Basalt Formation. This material is considered the darkest, deepest purple amethyst variety worldwide. Long stalactites with premium color are a double collector's classification.

The open display allows a direct view into the geode's interior. The stalactite geometry is thus fully visible, offering a gallery dimension on a large sightline.

A museum-quality Uruguayan collector's item with documented stalactite formation, full color depth, and rare geode growth pattern.
