Jewelers marks?

[moneymeister]

Just curious; I bought this akoya strand 2nd hard and noticed etching on the "J" of the fish hook clasp. It looks like LY55H and is repeated at the top. Any guesses what this means? I am wondering if this was somehow marked with the owner and 1955. The strand size would fit with that time. Thanks in advance for your 2 cents!

I've seen this sort of faint inscribing on other jewelry pieces. My best guess is it was for inventory control by the manufacturer...

Could it be when a strand was re-strung? a memo by the stringer, like watch repairers (back in the day when they were repaired and went tick) used to put a mark and the date on the inside of the case?

I used to collect old watches and they did scratch a service note with a date that made me wonder about this too. If it was re-strung in 55, this is an old strand.
