Good Inexpensive Tester
on October 26, 2011
Was not sure what to expect from an inexpensive tester but found it easy to use and effective. Especially after reading all the instructions (including the notes at the end). True, instructions could be better but certainly good enough to be able to run routine tests. For this price you cannot expect a tester that will give a complete and totally reliable test. For example, this tester will not identify synthetic moissanite (man made crystal with many similarities to diamond) but it will spot CZ and since CZ is much cheaper than moissanite stones this tester will be useful for many of us. But if you are concerned to discern difference between genuine diamond and moissanite then there are other testers that will do that job for you. We had some older jewelry and wanted to test to be sure which held diamonds and which did not. For this purpose it was extremely helpful. For those who like to frequent flea markets and garage sales looking for quality antique jewelry this could be an invaluable tool. Since moissanite started to be used in jewelry in 1998 it is only more recent jewelry that would need to be tested to distinguish moissanite from diamond.
