Large Deep Purple Amethyst Geode – 21.55 lb | Natural Uruguayan Specimen

A Commanding Deep Purple Amethyst Geode from Artigas, Uruguay

This 21.55 lb deep purple amethyst geode is the heaviest and most architecturally striking of its kind, sourced from Artigas, Uruguay. The crystal bed displays a natural color gradient — deep, near-black purple at the dense center transitioning to soft lavender at the outer edges — a rare tonal range that occurs only when the right mineral conditions align during formation.

What frames this gradient is an unusually wide band of white milky quartz that borders the entire crystal cavity. Clean, bright, and structurally pronounced, this quartz surround acts as a natural frame, drawing the eye directly into the deep purple interior. It is a geological composition that needs no enhancement.

The flat-cut base provides secure, stand-free display. At over 21 lbs, this is a commanding floor or shelf specimen — the kind of piece that defines a room rather than decorating it. One of a kind.
