Great amethyst geode in a metal stand with a beautiful rock crystal rim

An amethyst geode from Brazil with a distinctive rock crystal rim in a metal stand. A compact geode display in a classic showcase format.

Amethyst crystallizes in volcanic geodes of the Serra Geral Basalt Formation. Brazilian deposits in Rio Grande do Sul provide this material in a wide range of shapes and colors.

The rock crystal rim on the outer edge of the geode documents a secondary mineralization phase after the completion of amethyst formation. Clear quartz points line the violet cavity.

The metal stand is a curatorial staging decision. The geode is fixed in an optimal viewing position.
