Physical properties
Hardness: 6-7 (matrix) / 7 (vein); Color: Dark gray or green with a white band; Luster: Dull to vitreous; Crystal Structure: Mostly microcrystalline; Cleavage: None visible.
Formation & geological history
Formed through regional metamorphism or hydrothermal activity where a fracture in a pre-existing rock was filled by mineral-rich fluids (typically quartz), common in coastal and glacial environments.
Uses & applications
Mainly used as a pocket stone, decorative charm, or for spiritual/meditative purposes (Wishing Stones); also indicates geological tectonic activity.
Geological facts
According to folklore, a stone with a single continuous white line encircling it is a 'Wishing Stone'. It is said that if you make a wish for yourself and throw it into the sea, or give it to someone else, the wish may come true.
Field identification & locations
Identify by a single, continuous white band that goes all the way around the rock. Commonly found on pebble beaches or in riverbeds where erosion has rounded the stone.
