It stands for Yellow Lustrium, a Jewlers alloy
You lie to much!
Oh, dude, LTM stands for "Lifetime Warranty" on a Jostens ring. So, like, if your ring gets all wonky or something, you can probably get it fixed or replaced. It's like a little safety net for your bling.
LTM stands for "Layered in 14K Gold." It means the jewelry item is made of a base metal and coated with a layer of 14 karat gold. So, basically, it's like a fancy way of saying "gold-plated," but with a touch of mystery to keep you guessing.
