| Those are good for detecting cubic zirconia or other imitation diamonds, however to detect the difference between a man-made and a natural diamond you need a much more expensive tester and it has to be refrigerated down to almost absolute zero. Those machines start north of $10,000. Lab grown diamonds I'll have a serial number that is available to the general public, all the Jeweler has to do is look up the number lasered on the diamond and reference the database. Not saying that there may be a few out there that don't have a serial number on it, but the labs have all agreed to do it that way. I'm assuming the diamond cartel De Beers had a little something to say about that too. | |

Can you tell the difference between synthetic and real diamonds ?
