Physical properties
Hardness: 5-5.5 (Mohs scale); Color: Black or dark smoky brown; Luster: Vitreous/Glassy; Structure: Amorphous (non-crystalline); Cleavage: Conchoidal fracture; Translucency: Translucent when held to light.
Formation & geological history
Formed from rhyolitic lava flows that cool rapidly, preventing crystal growth. They are typically found embedded in a grayish-white perlite matrix. Most Western US specimens date from the Late Cenozoic Era.
Uses & applications
Used in jewelry making (beads, pendants), as metaphysical healing stones, and in flint knapping for arrowheads or surgical-grade blades.
Geological facts
According to legend, the stones were formed from the tears of Apache women mourning warriors who leaped from a cliff to avoid capture by cavalry; it is said that whoever possesses one will never need to cry again.
Field identification & locations
Identify in the field by their rounded, pebble-like shape within perlite deposits. When held up to a bright light source, they reveal a smoky, translucent brown or gray interior. Common in Arizona, Nevada, and New Mexico.
