I have over the years bought a lot on Ebay, many diamonds!, recently learned about fakes, there are many and I have quite a few, went through about 20 today, 5 fake!!!! passed the old diamond testrer, did  not pass my new tester ! Buyer Beware!!!

Before you panic, did you test diamonds you were sure of (perhaps ones with the Canadian polar bear ) with both testers?
