Physical properties

Hardness: 6.5-7 (chert) or 3-3.5 (barite); Color: Tan, beige, or sandy brown; Luster: Dull to waxy; Texture: Pitted, vesicular-like surface or wind-eroded (ventifact).

Formation & geological history

Formed through chemical precipitation in arid or marine environments. The pitted surface is likely due to differential weathering or wind abrasion (aeolian processes) over thousands of years.

Uses & applications

Geological collecting, home decor, and educational specimens.

Geological facts

While it resembles a seed or organic pit, its texture is characteristic of wind-sculpted stones known as ventifacts, commonly found in desert pavement areas.

Field identification & locations

Identify by its hardness (usually scratches glass if chert) and its unique pocked or dimpled surface. Often found in dry lake beds or high-wind plateau environments.
