Physical properties

Hardness: 6.5-7 (Mohs), Color: Translucent cream, beige, or white with dark inclusions, Luster: Waxy to vitreous, Structure: Microcrystalline, featuring scale-like surface patterns.

Formation & geological history

Formed in the cavities of volcanic or sedimentary rocks through the slow deposition of silica from groundwater. The characteristic 'snakeskin' pattern is created by surface etching and mineral inclusions during the cooling process.

Uses & applications

Used primarily for lapidary work, jewelry (beads, cabochons), energy healing, and as decorative pocket stones or specimens for collectors.

Geological facts

It is named for its distinct physical resemblance to the scales of a snake. Many specimens found in Oregon, USA, are actually weathered nodules of agate that have developed a wrinkled 'skin' due to chemical weathering.

Field identification & locations

Identify by the unique scale-like or wrinkled texture on the exterior. It is commonly found in desert regions of Oregon (USA), Mexico, and parts of India and Brazil.
