very large, dark, and very deep amethyst geode with double-terminated crystals that you can lie inside

A very large, deep dark amethyst geode from Brazil with double-terminated crystals. The cavity is so spacious that a person can lie inside, the interior fully lined with dark purple points.

Double-terminated crystals grow freely in the geode solution without being connected to the geode wall. Both ends form points; this constellation documents free movement of the crystal during mineralization.

Double-terminated crystals in amethyst geodes are a deposit-specific premium collector's feature. Such walk-in geode dimensions are a top rarity in the worldwide amethyst market due to their formation.

The Brazilian deposits in Rio Grande do Sul supply this museum-quality material. Volume, double-terminated crystal characteristic, and dark premium color intertwine here.

A museum-quality Brazilian collector's item with documented double-terminated genesis and architectural gallery dimensions.
