Review This Product
A wonderful tool.I have used the diamond tester and am excited with the results. However, the instructions didn't mention what the blue lines indict. My LED colors are red, yellow, blue (not green). December 20, 2014

Doesn't distinguish diamonds from moissanite?!If this instrument doesn't tell you if a gemstone is one of the most common fake diamonds out there, what is the point of using it?! Sheesh! Save your money and buy one that tests for moissanite! December 15, 2014

Quick and easy to useNo learning curve. Take the rubber cover off the tip, turn on, wait for ready light, touch tip to stone. It will beep and go to the blue color, the word diamond is in this area, if it is a diamond. I tested it with other stones to make sure it didn't activate with just anything. Does what it is supposed to do. Compact enough to take on the go. December 26, 2013

Worthy addition to my toolsI have been collecting various tools to help me with my gemstones. This is a worthy addition that had an unexpected benefit. I am getting more guests in my home as they all drop by for a cup of coffee and an oh-by-the-way stone in their possession. They want me to check to see if they happen to own a diamond. I am glad to have it as part of my gemstone toll kit. November 21, 2013

easy to use.it helps find your true values in your collection. Too bad it doesn't detect the difference between diamonds and Moissanite. Bit that means the moissanite is that good. April 22, 2013

LOVE IT..Mom must have sold her diamonds...Love it... works very easily....pop in a battery, read the instructions and start checking your jewelry. Mom evidently sold some valuable diamonds and replaced with junk (confirmed what I already suspected) Can't wait to hit the garage sales. April 06, 2013
