Physical properties

Formation & geological history

Silica-rich groundwater deposited chalcedony in rock cavities, commonly in volcanic rocks; agate deposits formed at various geological ages. The specimen has been cut and polished by a craftsperson.

Uses & applications

Used for carvings, jewelry, ornaments, and collectible lapidary pieces.

Geological facts

Agate is valued for its varied colors and bands; moss agate contains mineral inclusions that create plant-like patterns, though this piece’s visible pattern is subtle.

Field identification & locations

Identify by its smooth polish, waxy luster, translucence, and curved chalcedony bands; common sources include Brazil, Uruguay, India, and the United States. The carving obscures natural shape and makes provenance difficult to determine.
