Beautiful amethyst wing pair with calcite from Uruguay

An amethyst wing pair from Uruguay with calcite detail. An expressive geode pair display with two mineral phases, featuring white calcite tips growing out of the deep purple amethyst walls.

Wing pairs are formed when a geode breaks open along its central axis, presenting both halves like outstretched wings. The wing display transforms the geode pair into a showcase sculpture.

Uruguayan amethyst is considered the darkest, deepest purple amethyst variety worldwide. The calcite, as a secondary mineralization phase, grew on already formed quartz tips after the amethyst growth was complete.

Calcite is Mohs 3, significantly softer than quartz and acid-sensitive. The care of such multi-phase pieces follows the softer mineral component.

The Uruguayan deposits in Artigas and Salto supply this material from the Arapey Basalt Formation. The wing arrangement is a premium curatorial display in the collector's market.
