Rock Identifier: Gem Stone

What rock is that, and is it worth anything? Point your camera at any stone and know in seconds. Rock ID identifies rocks, minerals, gemstones and fossils from a single photo, then answers the two questions everyone actually asks: what is it, and what is it really worth? No hype. Most driveway rocks are worth a few dollars, and this app says so.
