Apache Tear

Physical Properties

Hardness: 5-5.5 (Mohs scale); Color: Black to dark brown, but translucent/honey-colored when held to light; Luster: Vitreous (glassy); Crystal Structure: Amorphous (non-crystalline); Specific Gravity: 2.3–2.6.

Formation & Geological History

Formed from rhyolitic lava flows that cool rapidly before crystals can grow. These specific rounded nodules are often found embedded in a grayish perlite matrix, formed by the hydration of obsidian over millions of years.

Uses & Applications

Primarily used for lapidary work, jewelry (pendants and beads), and as a popular collector's specimen. In metaphysical circles, they are used as 'grief stones'.

Geological Facts

According to legend, the name comes from a 19th-century battle where Pinal Apaches, facing defeat, rode their horses off a cliff. Their grieving families' tears turned into these dark stones when they hit the ground. Scientifically, they are just sub-spherical obsidian cores.

Field Identification & Locations

Identify in the field by looking for rounded, black, glass-like pebbles within crumbly, light-grey perlite. Hold a piece up to a bright light source; if it glows brown/amber and is translucent, it is an Apache Tear. Commonly found in Arizona and Nevada, USA.
