Does anyone with real tiffany and co jewelry know if the engraving (machine and hand) eventually wears away?

Also does the signature engraving that most jewelry has that says "tiffany and co" wear away also.if wear does occur how long does it take?

I've had mine for years and they still haven't. If it were to wear away, it would mean the silver is wearing away, too, which shouldn't be possible with real silver. If your jewelry is real, take it back to the store and they will fix it up for you (for free).
