Stone Agate Geode

Slice of banded agate with a pale lilac core and a gold edge.

This is an agate geode. It is semi-precious stone. Agate is a banded variety of chalcedony, a form of quartz, and slices of it are often polished to show its layers of color. Round, flat slice with concentric rings that shift from smoky brown to white to pale violet, with a crystalline centre. The edge is trimmed with a thin metallic gold border. The cut face is glossy and smooth.
