Not bad for the price
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. ... show more

Good quality, eazy to use
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.
