Diamond Tester, Professional Jewelers' Gemstone Detector, High Accuracy Diamond Checker Pen Professional for Jewelers, Gem Tester (Jewelry-Only Detection)

Simple to use and very functional. Great item. Very well made. Amazing size and quality.

Received product as described. Works very easy with easy-to-understand directions.

This does seem to work at least to let you know if it is diamond versus rhinestone. The instructions are missing information that almost made me return it... You need to have your finger on the metal plate and hold the item in your other hand for the metal alert to work. Using this information made the detector function properly and accurately.

Please don’t waste your money. I followed the instructions and my tester did not work. I was unable to return it in the usual way, which would be to go to Kohl’s. I would give them a zero star review if I could.

Kind of fun to play with for the price. I'm not sure I would bet my life on the accuracy of the results. It's fickle. I think it's kind of fun for reassurance, but if I really wanted a true answer, I would probably still have to take it to a professional.

Worked good. Impressed for the price. Good quality

Works well, just what I needed.

This is great for you to check your jewelry. It's a great value. Not sure why the battery died so quick. It seems to be accurate.
