Hallmarking precious metals, possibly the oldest form of consumer protection, was first developed to verify gold and silver content in coins, and soon became standard practice for jewelry. Today, while the physical stamping of jewelry is not required in the United States, descriptions that are provided by the seller must be precise, and not just when it comes to karat fineness. If it is not possible to visually distinguish between separate precious metals in the same item, then the amount of one metal, relative to other metals in the item, must also be disclosed. A quick Web search of mixed-precious metal products--in this case, gold and silver--reveals that the rules on how to describe precious metal content in fine jewelry are not always followed. Besides being unfair to jewelers who follow industry regulations, the inconsistencies hurt consumer confidence.
