Physical properties

Hardness: 6.5-7 (Mohs); Color: Gray, tan, and reddish-brown with scale-like patterns; Luster: Vitreous to waxy (when polished); Structure: Trigonal (microcrystalline); Cleavage: None.

Formation & geological history

Formed primarily in Western Australia as a sedimentary rock where silica-rich fluids permeated older rock layers, depositing microcrystalline quartz in distinct, scale-like bands over millions of years.

Uses & applications

Used extensively in jewelry as cabochons, beads, and pendants, and as a decorative stone for carving and collection.

Geological facts

The 'snakeskin' pattern is a result of chemical processes during formation that create a distinctive texture reminiscent of reptilian scales rather than actual fossilized skin.

Field identification & locations

Identify by the unique rounded, interlocking 'scale' patterns and high hardness; it is commonly sourced from the Windierilla Station area of Western Australia.
