Beautiful, handy amethyst druse in a metal stand from Brazil

A handy amethyst geode from Brazil with lilac-colored crystals, set in a clear quartz rim and an outer layer of white agate. The geode stands firmly in a sturdy metal stand.

Amethyst geodes from Brazil are formed as crystal-filled cavities in basalt lava. The back of the piece shows the original volcanic host rock in which the gas bubble formed about 100 million years ago.

The multi-layered structure of amethyst, quartz, and agate is typical for classic geode genesis: inwardly growing mineralizations from circulating solutions. A compact display geode with clear geological readability.
