Physical properties
Hardness: 6-7 Mohs; Color: Naturally grey or tan but coated in yellow, black, and white acrylic paint; Luster: Dull/Matte paint finish; Texture: Smooth, water-worn rounded surface
Formation & geological history
Formed via the erosion and smoothing of rock fragments in a river or coastal environment over thousands of years, subsequently hand-painted by a human.
Uses & applications
Decorative art, kindness rocks, hobby crafting, or as a paperweight.
Geological facts
This is a classic 'Kindness Rock' often left in public spaces to brighten someone's day. The underlying rock is likely a durable sedimentary or metamorphic stone selected for its flat, smooth surface.
Field identification & locations
Identify by the presence of synthetic paint over a naturally rounded, water-worn lithic substrate. Commonly found in craft stores or sourced from riverbeds.
