Contrary to it's name Goldstone is not a stone, but a type of glass made in a low-oxygen reducing atmosphere. It's origins aren't 100% certain, but one process for goldstone was invented in seventeenth-century by the Miotti family of Venice. However, according to legend goldstone was an accidental discovery by Italian monks, but there is no pre-Miotti documentation to confirm this. A goldstone amulet from 12th-century was discovered in Persia. You'll discover that wearing these ankers is a sparkling good idea.
