Are you sure you're reading 926 instead of 925? 925 is Sterling Silver. It's 92.5% silver and 7.5% copper. I've seen 926 in gold jewelry (usually Italy,) which means 22K gold. I understand if you see a 926 on any jewelry that is not YELLOW GOLD in color that it means it's plated over with another metal. You might want to take it to a jeweler or pawn shop and have it tested.Nice find, Breezie
