My fiancé and I purchased my lab diamond at a mall jewelry store after looking at many other online retailers such as brilliant earth, etc... we got the best deal there after all the discounts and the sale they were having. It is a 2ct lab diamond; G color, VS1, excellent cut. I was told it would test as a real diamond. I was at another jewelry store looking at wedding bands and I asked them to test my diamond because I had read of someone buying a ring claimed to be a real diamond and it turned out to be a moissanite. The jeweler said my ring was NOT testing as a diamond, but that some lab diamonds do not test real....is this true?!
