High Accuracy Diamond Tester and 60X Clip-On Microscope Magnifier Professional Jeweler for Novice and Expert - Diamond Selector II 9V Battery Included

Others out there are better

The controls were touchy, but it did a good job. I would recommend it.

Actually, this diamond tester functions as advertised and while it's not a Presidium either I or II it's worth every penny and more! I had one of the clip-on mini microscopes already as well as a 45x and a 16x also all of which are quite clear of view though they're all really a bit too small to use easily but for the price, generally under $5.00, you have no cause for complaint! In all, you can't go wrong in purchasing this combination!

This does work quite well but it feels kinda chinsey. You have to set the dial according to the temperature of the room and then the size of the diamond. It’s not just a turn on and go kinda thing. And you have to keep the little folded up instructions with it to have the setting info to use it correctly.

Only negative is shows Moissanite as real diamond

If you take the time to read the instructions, this product works great. I was a little worried based off some reviews claiming you need to spend hundreds to get an accurate one, well that was a lie. Within a few minutes of practicing I have easily been able to accurately separate pieces from real or fake with no gray area. So far this product has worked with 100% accuracy, even when testing every type of fake diamond. None even came close to a positive read. Cant wait to take this product to garage sales this summer!

Price was right and pretty simple to use!

It worked ONCE

Llego rapido y si funciona may bien! Grasias!!!
