Physical properties

Hardness: 7 on Mohs scale; Color: Pink; Luster: Vitreous to waxy; Crystal Structure: Trigonal (if crystalline, though this is a tumbled water-worn pebble); Specific Gravity: 2.65

Formation & geological history

Formed through natural weathering and tumbling of quartz minerals or sea glass in high-energy marine environments along beaches and coastlines over variable geological or recent timeframes.

Uses & applications

Commonly collected as beach treasures, used in lapidary arts, wire-wrapping, or crafted into unique coastal jewelry.

Geological facts

Pink pebbles found on beaches are often rose quartz, but can occasionally be weathered pieces of man-made art glass or sea glass, which shares a similar quartz composition if silica-based.

Field identification & locations

Found globally along sandy or pebble-rich beaches; collectors look for smooth, frosted textures and distinctive color variations washed ashore by tides.
