For all of those who may not know this as I did not. A lady at the jewelery store I take my findings to showed me a secret for testing diamonds without a tester. If the stone is large enough or you can see the sides you can test to see of real by placing the large part(what you see) on printed letters and if you can see any part of the letters in the stone it is not real. The true diamond does not reflect anything to a legiable form for you to recongnize. Since I did not know this I thought some of you may like this info for future use.
