Undulating Shape - Epitaxial Goethite Calcite

Impressive, undulating white quartz edge, and amusing lavender color amethyst. Its icy calcite resembles flower petals, furthermore, the coated in black goethite calcite turns this piece into an absolute delight. The combination of black goethite arranged in straight lines over calcite is particularly rare and mainly found only in Uruguay. These mineral arrangements can be referred to as "skunks" by gemstone collectors.
