This is probably a stupid question but I'd rather ask you ladies versus taking it to the store. Is there any way I can tell if a ring is real gold/real diamonds? I'm packing up the dorm and started looking through my jewelry box and found a ring I forgot I took from my mom a long time ago. Its a gold band with emeralds and diamonds, but its kind of beat up so I assumed it was costume jewelry. Is there any way to tell for sure though?
