I found all of the pieces worked as stated. I was particularly impressed with the portable microscope. I can actually read certification numbers on the girdles of the diamonds. Amazing! The diamond tester seemed like the first ones that came out many years ago. I tested with known samples before I rested results on it. Then along came a Moissanite. A moissanite tests as a real diamond. I cannot figure out why. They are made from different materials. I tried warming the stone first. No different. So if you use it rule out moissanite.

EVERYTHING about this set just did not feel right. Way it was supposed to be held just felt like wrong. Then I “tested” it with a huge family diamond ring that has already been tested and I have a written appraisal we KNOW it’s been in the family for over 125 years. Appraisal showed the largest diamond was 5 karats set in platinum with 3 karats in a design around center diamond. We tested and it failed with an appraised piece of jewelry! Appraised a total of 3 times in last 25 years, so we KNOW this tester is not of good quality.

It arrived in perfect shape and it works fine. Still playing with it.

missing the mini scale , plus the magnify naver works, no 9 v. include it, also it looks that this item was use before

Good product for the price. It has to warm up to get an accurate reading. It helped me determine if a ring was fake which I returned. This product will save you money. It saved me hundreds.

I replaced my tester an scale after loose the original to hurricane damage

Good product All elements are working properly

A bit too expensive

I was confused because this is meant to be a diamond tester but I placed it on metal by accident and it hit the top telling me that the metal was a diamond crazy right😵‍💫

le détecteur et la balance sont tres biens,c'est la loupe qui laisse a désirer.Suis contente quand meme de mon achat.

The unit works, but testing a diamond, zirconia is all shown as a positive diamond. So, it works, but not correctly.
