Rare White Amethyst Geode Pair with Crystal Hedgehogs and a Great Rim

A white amethyst geode pair from Brazil with crystal urchins and a distinct rim. An unusual color variant in a dual-chamber presentation.

White amethyst geodes are a deposit-related color variant with a lower iron concentration. The light coloring indicates specific solution conditions during the mineralization phase and occurs in only a small percentage of Brazilian production.

Crystal urchins are dense, radially radiating aggregates of smaller points. They grow like hedgehog spines from the geode floor into the cavity. The urchin shape is a distinct growth geometry with its own collector profile.

Brazilian geodes from Rio Grande do Sul provide this material. The geode pair configuration with two halves allows for a 360° presentation with a full view of both cavities.
