GemOroGemoro UltraTester Diamond and Moissanite Tester

Excelente calidad y relacion precio / beneficio

Used as instructed but something seemed off about this device. I tested a battery head and the device read it to be a diamond smh total waste of money.

Estuvo fallando en las mediciones de diamantes.

used it once , and it worked just fine . took the batteries out and put away , came back to use it again after 3 months and it did not work with rechargeable or the regular AAA batteries . It does not charge the batteries , it only run with the USB cable ! . Very disappointed , don't know what do now .

Wow. Simple and very easy to use. Thanks Rich
