Unique Amethyst Geode with Calcite Flower

A Uruguayan amethyst geode with a calcite flower. The calcite flower is a prominent secondary detail within the geode's balanced block geometry.

The calcite flower is a radiating scalenohedral aggregate that crystallized after the amethyst had finished growing in the already formed geode. Such two-phase mineralizations document changing solution chemistry over geological time scales.

Uruguayan amethyst from Artigas and Salto is the classic premium provenance worldwide. The material classification assesses color intensity and secondary detail characteristics.

The calcite flower as a premium detail in the balanced three-axis geometry makes the piece a mineralogically instructive display item. The polished exterior highlights the internal structure with strong contrast.
