Large Amethyst Geode with Quartz – 26.83 lb | Natural Uruguayan Specimen

The Most Geologically Complex Specimen Amethyst Geode from Artigas, Uruguay

This 26.83 lb natural amethyst geode from Artigas, Uruguay is the most geologically complex specimen in this collection — and the heaviest. The upper portion displays large, well-defined purple amethyst crystal points with exceptional clarity and faceting, positioned above a massive natural white quartz formation that occupies the lower third of the piece.

Multi-Generation Mineral Growth — Lavender Druzy and Transparent Quartz Points

What makes this specimen truly rare is the secondary mineral activity visible within the quartz zone: a fresh growth of lavender druzy amethyst has formed directly on top of the white quartz, alongside elongated transparent quartz points emerging from the center. This layered sequence of mineral generations — basalt host, white quartz, amethyst cluster, secondary druzy — documents an unusually active geological history inside a single specimen.

The clean white chalcedony exterior wraps most of the piece, providing a bright natural contrast to the purple crystal face. The flat-cut base ensures stable, stand-free display. At nearly 27 lbs, this is a floor-level or large-shelf statement piece. One of a kind.
