Very useful if you are a jewelry buyer and need to check them before purchasing. Highly recommended

This tester works, but the instructions could be so much better. At first I thought it didn't work, because nowhere in the instructions does it tell you to remove the cap covering the tester tip. So be sure to remove the plastic cap before testing and jewels

It’s lightweight and not very bulky. I purchased this because of the great price. It comes with a carrying case but plan on getting a hard case down the road. The tip for the detector has its own protective cap on it which is nice. Battery was easy to install and instructions were easy to understand. Not sure on durability as I haven’t put it to the test but it seems okay. Accuracy seems on point with my other one. The brightness for the screen is good.

This is very sensitive to temp which makes it kind of hard to calibrate. However, once it is calibrated, it seems to work well on everything but earrings (probably due to stud blocking electricity flow). I tested on known diamonds (rings/bracelets) and known fakes and it was accurate only after calibration (meaning use a known diamond to get it to temp and accurately reporting it as a diamond). I would not use this without calibrating each time you use it as it is very easy to get a false reading and that could be a costly mistake. (I did not test using loose stones and I would not trust this for that at all as it seems very sensitive).

This is a cheap tester and you get what you pay for here, it is not accurate. I work in a jewelry store and have access to a more expensive and as it turns out, much more accurate tester.This tester alerted 'diamond' on CZ, white topaz, and white sapphire (loose stones, so not touching any metal), but failed to alert on several real diamonds (that alerted on other testers and are independently certified). Not enough pressure and it won't alert on genuine diamonds, but too much pressure and it alerts on everything else and the difference between not enough and too much is a pretty small margin.The other positive reviews leave me to wonder if I just got a dud, which I hope is the case, but I would waste the time and money trying again on it.

Love this when I went shopping the guy tried to sell me fake diamonds. His diamond tester said it was real mine said fake. Mine was accurate because I tested my earrings before and some other jewelry. In my purse it goes from now on
