Physical properties
Hardness of 7 on the Mohs scale due to the quartz band; dark grey to black host rock with a contrasting white or translucent quartz band; vitreous to dull luster.
Formation & geological history
Formed when hydrothermal silica-rich fluids filled fractures in pre-existing sedimentary host rock, followed by weathering and water tumbling.
Uses & applications
Commonly collected as a novelty, talisman, or utilized in wire-wrapped jewelry.
Geological facts
Folklore dictates that if the single continuous band wraps entirely around the stone, one's wish will come true.
Field identification & locations
Easily identified by a distinct single mineral band circling the pebble; found in riverbeds and ocean beaches worldwide.
