I recently got my hands on this diamond tester pen, and I couldn't be more happy with it. As someone who loves jewelry, this tool has made identifying genuine diamonds, moissanite and CZ a breeze. It truly does differentiate CZ from Moissanite and Moissanite from Diamonds! It offers precise readings that help me differentiate between real diamonds and imitations effortlessly. The pen is incredibly easy to use, providing quick and accurate readings that give me confidence in my purchases. It fits comfortably in my hand, and the sleek design makes it a joy to use. I also appreciate how portable it is; I can take it anywhere and test stones on the go to show friends. Just a single use could save you from fraudulent stones claiming to be one thing and then are something else. Everyone should have this tester at home. I cannot say enough good about this item. This little gadget has truly elevated my jewelry-buying experience so I never get taken. You gotta get one. Highly, highly recommended. : )

Not the best quality assurance happening with this device.I really like that this model has a plug-in feature, so as to not require a 9v battery. I really want it to work, but I had to use a back up unit, because the first one I received stopped working properly the second time I tried to use it, within only a few days from my box opening and testing it out.My first unit appeared to work when I first tested it out using a diamond ring, then when I went to use it on a stone I had just received a few days later, the audible tone (indicating the stone is a diamond) would not come on. I tried the diamond ring, and nothing. Apparently, the speaker was a one-time use. I returned it for a replacement. When I took out the second unit, I could here something rattling/loose inside. I opened the battery compartment, and a screw dropped out. Wow!Also, the first unit came with a 9v battery, but the 2nd unit did not. Like I said, quality assurance is really absent in the production of this model.

First of all, I despise when a seller uses one listing over and over for different items so they can retain their high reviews.That being said, I purchased this particular diamond tester because I didn't have to mess around with batteries and could just plug it in.I plugged it in, adjusted the size setting and tested it out on my already certified wedding/engagement ring and then a Moissanite ring. Both registered and emitted the noise they were supposed to. Then I readjusted for size and attempted to test several pairs of diamond earrings (from a very well known jewelry store) I have. No reaction at all, no matter what I tried.I then whent back to my wedding set and it wasn't registering anymore, either. I pushed down harder and it finally read, but then stopped again.You get what you pay for, and apparently this one is just too cheap.Returning.

I recently purchased the HMKIS Diamond Tester Pen with the accompanying 60X Mini LED Magnifying glass, hoping to accurately assess the authenticity of diamonds and gemstones. While this set offers some functionality, it has a few limitations that prevent it from receiving a higher rating.On the positive side, the diamond tester pen is compact and easy to use. It provides a quick indication of whether a stone is likely to be a real diamond or a simulant based on thermal conductivity. The results are displayed through a series of LED lights, making it relatively simple to interpret the readings. This feature can be helpful for novice users who are just starting to explore the world of gemstone testing.The inclusion of the 60X Mini LED Magnifying glass is a nice addition, as it allows for a closer examination of the stones. It provides decent magnification, which can assist in identifying any flaws or inclusions in the gemstones.However, there are some limitations to consider. Firstly, the accuracy of the diamond tester pen is questionable. While it can provide a basic indication, it is not as precise as more professional-grade diamond testers on the market. It may struggle with certain types of stones or yield inconsistent results, which can be frustrating for expert users who require more accurate assessments.Additionally, the build quality of both the diamond tester pen and the magnifying glass leaves something to be desired. They feel somewhat flimsy and not as durable as I would have liked. This can be concerning, especially if you intend to use them frequently or rely on them for professional purposes.Lastly, the instructions provided with the set are somewhat lacking. They are not as detailed or comprehensive as I would have preferred, particularly for users who are new to gemstone testing. It would be beneficial to have clearer guidelines and additional information on interpreting the results.In conclusion, the HMKIS Diamond Tester Pen with the 60X Mini LED Magnifying glass is an average set for assessing the authenticity of diamonds and gemstones. While it offers some functionality and can be useful for beginners, its accuracy and build quality are questionable. If you require more precise and reliable results, it may be worth considering higher-end diamond testers on the market.For novice users or those who need a basic indication of a stone's authenticity, this set can serve its purpose adequately. However, if you require more professional-grade equipment or expect greater accuracy and durability, it may be worth exploring other options in the market.

Als wir das Gerät ausprobiert haben, mussten wir leider feststellen, dass die Lupe ihren Zweck nicht erfüllt. Der Gerät selbst ist in Ordnung. Wir wollten diesen Produkt zurück geben, nun leider wurde uns gesagt, dass wir den Rückversand erstmal selber übernehmen müssen. Die Sendung kam aus USA und den Rückversand hätte uns noch 50€ gekostet, von daher haben wir diesen Artikel behalten. Ich wollte den Verkäufer gerne kontaktieren, aber dies ist auch nicht möglich.....
