Unique amethyst geode with many agate eyes in a metal stand

An amethyst geode from Brazil with many agate eyes, presented in a metal stand. Several concentric agate eyes are embedded in the outer wall of the geode, each like a small mineralization core in itself.

Agate eyes form from micro-geodes in the original lava bubble, which were later cut open by the main cavity. Each eye documents its own small solution phase.

Amethyst crystallizes in the volcanic geodes of the Serra Geral Basalt Formation. Brazilian deposits in Rio Grande do Sul supply this material in the agate eye banding.

The metal stand fixes the piece in an optimal viewing position. The compact size is suitable for display in showcases or on desks.

A Brazilian collector's item with multiple agate eyes, documented micro-genesis, and curatorial presentation.
