Physical properties

Formation & geological history

Formed when a secondary mineral (usually quartz or calcite) fills a fracture or crack in a host rock through hydrothermal activity. This specific specimen has been further shaped and polished by water erosion, likely in a river or coastal environment.

Uses & applications

Primarily used as pocket stones, decorative beach stones, and in metaphysical practices as 'wishing stones.' Not typically used for industrial purposes.

Geological facts

In folklore, a wishing stone is a rock with a continuous white line encircling it. It is said that if you trace the line with your finger while making a wish, it will come true.

Field identification & locations

Identify by looking for a single, unbroken white band that completely circles a smooth, water-worn darker pebble. Commonly found on pebble beaches or in glacial till deposits.
