Physical properties

Hardness: 3-7 (depending on vein vs. host), Color: Grey/Black with a white/cream band, Luster: Dull/Earthy, Crystal Structure: Microcrystalline, Texture: Fine-grained, rounded by water erosion.

Formation & geological history

Formed as fine-grained sediment in low-energy aquatic environments. The white line is a mineral vein that formed later when mineral-rich water filled a crack in the rock and crystallized. The rounded shape is the result of mechanical weathering in a river or beach.

Uses & applications

Primarily collected as keepsakes, pocket stones, or for decorative use in landscaping and aquariums.

Geological facts

In folklore, a stone with a single continuous white band encircling it is often called a 'Wishing Stone.' Legend says if you make a wish and throw it back into the water, or give it to someone else, the wish will come true.
