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.....

This diamond tester seems to differiate real diamonds from fake, no problem. For such a low price I was of course skeptical, but after usiong it on several different specimens I find it to be accurate. The instructions have a few typos etc. but still very understandable. Also it comes with a jewelers loupe, which again I was skeptical of, but turns out works great also. it has a led light and excellent magnification. Would reccomend if your just a hobbyist. In adddition, this model comes with a 9v battery which powers its operation. It also comes with a usbc cord in case you dont want to use athe battery, I like the portablility of the 9v personally.
