Apache Tears - Obsidianites+Perlite.
Apache tears are rounded pebbles of obsidian or "obsidianites" composed of black or dark-colored natural volcanic glass, usually of rhyolite composition and bearing conchoidal fracture. Also known by the lithologic term "marekanite", this variety of obsidian occurs as subrounded to subangular bodies up to about 2 inches in diameter, often bearing indented surfaces. Internally the pebbles sometimes contain fine bands or microlites and though in reflected light they appear black and opaque, they may be translucent in transmitted light. Apache tears originate from siliceous lava flows, lava domes or ash-flow tuffs, often in close association with or embedded in, gray perlite. The spherules occur as cores within perlite masses that typically exhibit texture of concentrically curved, onion-skin fractures.

Obsidian is considered a durable material and can be safely cleaned using a soft cloth and soapy water. Soap residue can build up on it, so rinse well and polish after. As with most gemstones, ultrasonic cleaners and steamers are not recommended. Take care to store obsidian in a soft case away from hard objects as it can be easily scratched.
