The answer is "YES" as required by Law (the term "Sterling" MEANS 0.925 (92.5%) Pure Silver Content in the metal. Anything else would be ILLEGAL. So that ".925" stamp on the item is your assurance of legal compliance (otherwise the jeweler could be thrown in prison if they claim anything NOT .925 is "Sterling"). HISTORICAL FACT: the term "Sterling" comes from the official coinage of the British Empire, also known as "Pounds-Sterling" because every silver coin minted by the British Crown was a full .925 (92.5%) Pure Silver -- required by Law and punishable by DEATH if anyone ever minted a silver coin in anything but 92.5% Pure Silver. In contrast, U.S. silver coinage was 90% (0.900) Pure Silver until 1964 when it was changed to 65% and then in 1965 Silver was completely removed from U.S. coinage meant for circulation.
