Large amethyst geode pair in the shape of angel or butterfly wings in a metal stand

A gigantic amethyst geode pair from Brazil, opened like a pair of wings and mounted in a sturdy metal stand. An architectural collector's display of museum-like dimensions.

Amethyst crystallizes in volcanic geodes of the Serra Geral Basalt Formation from silica-rich solutions over millions of years. The Brazilian deposits in Rio Grande do Sul provide geodes of this size. The selection of a wing-shaped configuration is a curatorial cut decision.

The arrangement as a pair of wings is a deliberate display. The metal stand system holds the two halves in the geometry in which they originally formed the closed geode. The mirror-image growth symmetry thus becomes legible again.

Such premium geode pairs are classified as angel wing pairs in the collector's trade. They are considered the pinnacle of the amethyst display category.

An architectural collector's item of museum-like dimensions, suitable for reception areas or gallery spaces.
