Great amethyst geode in perfect color and with large crystals

An amethyst geode from Brazil in premium color with large individual crystals. The striking feature is the pronounced points, which significantly exceed the usual Brazilian standard.

Amethyst crystallizes in volcanic geodes of the Serra Geral Basalt Formation. Large individual crystals document exceptionally long growth phases with stable solution conditions.

The premium color is created by iron substitutions in the quartz lattice. Premium classification evaluates color intensity, clarity of the crystals, and the cavity geometry of the geode.

Brazilian deposits in Rio Grande do Sul supply this material. The slender column geometry concentrates the color effect in the vertical axis.

A Brazilian collector's item with premium color, large individual crystals, and gallery format.
