Physical properties
Hardness typically 3 to 7 on Mohs scale depending on mineral composition, color ranges from grey to tan and brown, dull luster, amorphous or cryptocrystalline structure, often features a natural hole carved out by water erosion.
Formation & geological history
Formed through sedimentary deposition over millions of years, with the distinct hole created by water rushing against a softer mineral inclusion or fossil within the rock until it eroded completely through.
Uses & applications
Traditionally used as a protective talisman or amulet in folklore; valued by collectors, pagans, and folklorists.
Geological facts
Also known as an adder stone, holey stone, or eye stone, these rocks have a rich history in folklore where they were believed to protect against magic, nightmares, and evil spirits.
Field identification & locations
Found near bodies of water such as rivers, streams, and beaches where continuous water action creates the perforation; identified visually by a natural hole piercing straight through the rock.
