Physical properties

Hardness: 6.5-7 (Mohs scale), Color: Creamy white to reddish-tan with dark brown or black veining, Luster: Vitreous to waxy, Structure: Microcrystalline quartz, Specific gravity: 2.58-2.91

Formation & geological history

Formed primarily as a sedimentary rock through the accumulation of silica-rich marine organisms or volcanic ash that undergoes petrification. The unique veined patterns are caused by iron and manganese minerals seeping into fractures over millions of years.

Uses & applications

Commonly used in lapidary work for cabochons, beads, and pocket stones. It is also a popular specimen for collectors and practitioners of metaphysical crystal healing.

Geological facts

Despite its name, it is actually a variety of chert. The name 'Snakeskin' originated from the patterns of the veins which resemble the scales and textures of a serpent. It is often found in riverbeds as water-worn pebbles.

Field identification & locations

Identify in the field by its high harness (it will scratch glass), its smooth, waxy feel when polished, and the characteristic dendritic or scale-like veining. Commonly found in Western Australia and parts of the United States.
