Physical properties
Hardness: 6-7 (quartz vein) vs 5-6 (host rock); Color: Grey-green host with a white or cream band; Luster: Dull to waxy; Texture: Fine-grained, water-worn/rounded.
Formation & geological history
Formed when minerals (quartz or calcite) precipitate from hydrothermal fluids into fractures of a host rock, typically during regional metamorphism or volcanic activity. This specimen shows significant river or beach abrasion.
Uses & applications
Primarily collected as a lucky charm or pocket stone; also used in decorative landscaping and lapidary art.
Geological facts
Folklore suggests that if you find a stone with a continuous white ring encircling it, you can make a wish. The white line represents a 'path' of energy through the stone.
Field identification & locations
Identified by a distinct, continuous band of white mineral cutting through a darker host rock. Frequently found on cobble beaches and in glacial till throughout high-latitude coastal regions.
