Gold necklace with 376 stamped on it what does it mean?

Oh, dude, that's easy. So, when you see "376" stamped on a gold necklace, it typically means it's 9 karat gold. Yeah, like, it's basically just telling you the purity of the gold. So, you know, it's not like a secret code or anything, just a way for you to know what you're working with.
