What does 585 mean on silver?

What 585 means on silver may be surprising. The hallmark 585 doesn't refer to silver at all. It actually indicates that something is produced out of 14-karat gold, which is 58.5% pure gold and 41.5% alloy. If you have a piece of jewelry or another item that is silver-toned and has a 585 stamp, it is likely to be 14-karat white gold rather than silver.
