Physical properties

Host rock varies in hardness and color. The white vein is typically quartz, which has a Mohs hardness of 7, vitreous luster, and is usually white or colorless in this context.

Formation & geological history

Formed when mineral-rich fluids (often silica) flow through cracks in existing rock and crystallize, forming a vein. Over time, the rock is weathered and tumbled by water into a smooth pebble.

Uses & applications

Primarily collected as a novelty or talisman (a 'wishing stone'). Smooth river rocks are also used in landscaping or decorative displays.

Geological facts

Folklore dictates that a rock with a continuous white line wrapping all the way around is a 'wishing stone' and can grant a wish.

Field identification & locations

Identify by a solid white stripe (usually quartz) running continuously around a polished or water-tumbled stone. Commonly found on beaches or in riverbeds where rocks are naturally tumbled.
