Very dark Uruguay Amethyst Geode with Agate Eye

A very dark Uruguayan amethyst geode with a distinct agate eye. A rare special form, a perfectly circular agate island in the middle of the amethyst field.

Agate eyes form when a second, smaller cavity exists within the main geode during crystallization. This mini-geode first fills with silica agate bands before the surrounding amethyst growth begins. The result is a sharply defined eye in the crystal field.

The color of the surrounding amethysts is deep violet, almost burgundy. This makes the contrast with the light agate eye particularly effective. It looks like a sun symbol in a dark field.

Agate-eye geodes from Uruguay are rare enough that we only stock one or two per year. The deposits in Artigas are known worldwide for the darkest amethyst colorations.

A Uruguayan collector's item with didactic depth, pronounced premium coloration, and a sharply defined agate eye.
