I'm not sure if it is a diamond. I think it is. But if it is, it's huge for an earring. Like a carat. I put it next to my diamond earring though and they are like identical almost.
I found it on the stairs outside of my apartment. I am going to call the leasing office and tell them if someone calls about it to let me know. There is only one other apartment that uses those stairs - it's across from me so I am going to see if it's hers (she wasn't home last night)
But other than taking it to a jeweler is there a way to tell if it is real? I hate to spend time trying to find the owner if it's just a CZ. Although other than what I am planning on doing already what else can I do? If it is a diamond whoever lost it is probably pretty upset.
I looked at it again last night and it has something written on it "S & 1/" where the 1/ looks like it is supposed to be a fraction but there is no denominator. And it's not gold, but my diamond earrings are set in platinum so it could be platinum. Going to take it to the jeweler where I sold my ring next week.
