If you find jewelry labeled sterling silver plate, it is legally invalid. A retailer may ONLY call something sterling if it is a solid ratio of 925 parts of silver per 1000. It does not count if the interior of the jewelry is base metal. It is still silver plate. Nothing more- and donât let anyone try to sell you something different.
