Physical properties
Hardness varies from 3 (limestone) to 7 (quartz) on the Mohs scale. Colors range from white and gray to tan and brown, featuring a smooth, water-worn luster.
Formation & geological history
Formed through the mechanical weathering and fluvial transport of parent rock over thousands of years, resulting in rounded clasts.
Uses & applications
Widely used in landscaping, ground cover, drainage systems, and decorative gardening.
Geological facts
These tumbled rocks are harvested from ancient riverbeds and beaches worldwide. The smoothing process is driven by hydraulic action and abrasion.
Field identification & locations
Identified by smooth, rounded edges and varied mineral compositions. Common in garden centers and alluvial deposits.
