I had to send my ring back to Kay's because the diamond became loose when I knocked it on a counter and I got it back a week later (over the weekend). Well, when I got it back and ever since I got it back, I swear it's not the same diamond!!! The diamond I was proposed with was soooo clear! On the certificate of the diamond it's classified as colorless. And now, it just looks weird! It doesn't shine the way it used to in the light. I want to take it back to check the serial number and take it to a jewelers to check if it's real. I hated that Kay's had to send it out to get serviced and now I'm paranoid that it was switched. I swear it's not the same diamond!! To ease my mind til I can take it in, does anyone know how to tell if a diamond is real? Without the microscope.
ETA: just got out of a jeweler. He showed me my ring under the microscope and my serial numbers are the same!! Thanks God! He explained that the reason for the lighting difference is because they cleaned it to look brand new. He also explained the at home ways to check a diamond like the whole fog thing, the rainbow color stuff(he said not to trust those methods because they'll make you paranoid!!). Mine was picking up other colors that it didn't before (which was a reason I thought it was different) and he said that when it's cleaned like brand new it'll shine differently than when it has been handled. My band did come back with damage to it (which didn't help with me thinking it was different). He showed me how the damage was done. The pliers used to hold the ring to tighten the diamond damaged my band. So I do have to take it in to get that fixed, but I'll pass. I can live with that damage. He told me that it does happen, when rings will get switched, so he told me I can come anytime I need adjustments and he'll help me out for free. Everything they do is in store! Thanks everyone for the support, I was going crazy.
