The tester does differentiate between diamond or moissanite as opposed to cubic zirconia. The loupe has decent magnification and the UV Light is a nice touch (some, but not all diamonds fluoresce). The additional magnification tool is fun to play with. I’m pleased enough with this purchase.

The boxing presentation was very cheap, however, the tester works perfectly. It was very accurate in determining a real diamond.

I’ve been selling loose Diamonds wholesale in NYC, for over 25yrs. I needed a new loop, and I can always use the Diamond detector pen. The pen is always helpful for my customers to have peace of mind.

It was extremely difficult to understand how to use it but the magnifying loop was very high quality. I would recommend it to someone experienced and for the price, the loop would be worth it. The loop gets 10 Stars
