Large Amethyst Geode with Agate – 28.31 lb | Uruguayan Purple Crystal

Vibrant Purple Amethyst Geode with Rare Green Agate from Artigas, Uruguay

This 28.31 lb purple amethyst geode from Artigas, Uruguay combines a vibrant, evenly saturated crystal cluster with one of the most distinctive agate formations in this collection. The upper face is packed with well-formed amethyst points in a rich, classic purple — consistent in color from edge to center, with strong metallic flash across every facet.

Rare Green-Banded Agate with Agate Eye — Uncommon Color in Uruguayan Material

What sets this piece apart geologically is the rare green-banded agate that runs along the base of the specimen. The concentric grey-green rings, including a perfectly formed agate eye, are an uncommon color expression in Uruguayan material — most agate banding in these geodes appears in cream or beige tones. This green variant signals a distinct mineral composition during formation and is highly valued by collectors who prioritize geological rarity over color alone.

The flat-cut base provides stable, stand-free display. At over 28 lbs, this is a substantial floor or shelf specimen. One of a kind.
