Diamond Tester Jewelry Gem Stone Tester Moissanite Tester Professional 2pt Jewel Stone Combo Tester Kit for Diamond, Moissanite, Metal and Gemstone Selection - High Accuracy Jeweler Test Meter Device

Seems to work, I tested items that I knew. Definitely pays when you don’t buy the cheapest!

The media could not be loaded. No es certero así que no lo recomiendo por el precio de $10 puedes obtener uno que hace lo mismo, este tester leía mis diamantes como moissanite (es un anillo popular de Kays jewelry de diamante naturales)

Works real well been using it for months its pretty consistent, I go back and test other stones every so often, it also is comparable to another tester I bought here on amazon and is reading the same results the other tester I have cost $200.00 and its the same findings.

I bought this jewelery tester so I can tell what is real and what is not from my own personal jewelery collection. Over the years I have bought a number of diamond stud earrings, and got some from a family member. Even I could no longer tell what was cubic zircon and what was real. Right out of the box, put batteries in, charged it up and put it to work on items I knew were real. It was accurate each time I ran the test. Even tested some costume jewelry, the device was not easily fooled! So far, I have to say I am pleased with this purchase, and hope it continues to do it's job! Although somewhat pricey, sometimes you get what you pay for! It's a little chunky, and you have to learn how to hold it precisely to get accurate results from testing. Keep that in mind.

As a professional jeweler that specializes in high end custom pieces, I hate to say that this tester is absolutely not accurate at all nor is it the easiest to use. For $100 I expected better.Smaller real authentic diamonds sometimes test as moissanite and larger moissanites often test as authentic diamonds.Moissanite will sometimes always read as Diamond on other testers, especially if it’s good moissanite but diamonds should never read as moissanite.In addition the prong can be weird to work with sometimes and no different prongs means if it doesn’t work for the piece you’re trying to test that you’re stuck with it. It would’ve been nice to see a few different prongs for properly working with different gem sizes.All and all, this is no different from the $20 tester you can get on here.

Works best on larger stones. Small stones were tedious and difficult to get a reading on, in some cases could not get an accurate reading. Good for home use to sort out jewelry, but I would not use professionally. I was glad I bought it to sort out my earrings and find what I thought were a missing pair of diamonds mixed in with some white sapphires.

A better one would be much more expensive— this one very good for price
