Determining if the stones are genuine diamond is not rocket science. If in centuries past people in the gem trade were able to do it, how much more in these days and age-- with all the high tech tools available even to the ordinary guy who's in the trade? Rough diamonds are of no interest to local Philippine jewelers for obvious reasons-- nobody would buy them uncut and unpolished and unmounted. Besides, the route to Tel Aviv or Antwerp is long before such stones will satisfy the time-honored criteria of the 4 C's. It's amusing to note that the polishing of sub-carat smuggled stones from illegal artisanal diamond miners in Africa is mere a village-level cottage industry in India. Suggestion: why not post a picture of these stones for the rest of the TreasureNet browsers to appreciate and to "render judgment"? Just for fun. Or whatever.
