Physical properties
Hardness: 5-5.5 (Mohs scale); color: black to smoky dark brown when held to light; luster: vitreous/glassy; crystal structure: amorphous (none); cleavage: none; specific gravity: 2.35.
Formation & geological history
Apache tears are rounded pebbles of obsidian formed by the rapid cooling of silica-rich rhyolitic lava flows. They are typically found embedded in a gray perlite matrix.
Uses & applications
Commonly used in lapidary work, jewelry (beads and pendants), and as popular specimens for crystal healing and metaphysical collections.
Geological facts
Legend claims that when Apache warriors were trapped on a cliff and chose to leap to their deaths rather than surrender, the tears of their families turned to stone upon hitting the ground.
Field identification & locations
Identify by their sub-spherical shape and smokey translucency when held against a strong light source. Commonly found in Arizona and New Mexico, USA.
