I bet you’ve been jewelry shopping and suddenly saw some code on a bracelet or a necklace. Maybe 228 or 925. Does this mean you’re being followed by MI-5? Or that you have a Bingo? Is there a secret 925 jewelry code?
Well, these are actually called a hallmark. It’s any little number code etched into a piece of metal used for fashion jewelry. The whole thing comes from an old English tradition of metal smiths having to take their wares into a board that certified their quality. The board would then stamp a hallmark on them.
