The Zerothustra

On Terra, a single cut of polished sunstone was worth a small fortune. Even here, they brought respectable prices from the zerothustra company's gem buyers. The scanner gave the uninterrupted pattern of homogenous structure. Picking it up with the lifter, he swung it and threw it into the stream. On the 15th chunk, he got an interruption pattern that told him that a sunstone, or something, probably something, was inside.
