Color: Tester
I purchased this item because I had realized I have been burned a few times on buying jewelry that was claimed to be genuine. This item does not only test for diamonds, but you can also gauge the gemstones with this as well. If you know what the hardness of a sapphire or opal is, you can use this to gauge whether or not it's genuine.

Ex. The hardness of a diamond is 10. If you know that corundum (ruby/sapphire etc) is a 9 and you test the stone and it ranks up there near a diamond but not quite, then you can assume that the gemstone you're testing is a genuine ruby or sapphire. However, if the "Ruby or sapphire" gemstone ranks very low, you can almost bet that it is maybe a quartz or topaz. Of course, this isn't an exact science with the tester, but it will give you a good idea of if your gemstone is what they are claiming it to be. Hardness scales of random gemstones can be found online everywhere so you can use those for references.

The diamond tester, I have found to be rather accurate. You do have to be careful with this item, since if you are trying to test diamond CHIPS or very small diamonds in large settings, and it hits the metal it will go off with a rather loud, continuous beeping noise to say "Error" that it's hitting the metal.

Suggestion: Use the tester on a genuine diamond (one you're certain is diamond) so you can get a feel for what it sounds like when it hits the 10 spot on the scale and what sound it makes. Also, try to test it on a metal to also see what it sounds like. Once you know how to read the tester, it'll be very easy to use. Instructions come with it and you can find YouTube videos that will show you how to use this as well.

Turn on tester. Set on level surface and wait. 1 red light will come on.

I have not read the other reviews so mine is unbiased. I am a gemologist and tested this instrument on 9 different gemstones.
It passed the test on all gems except moissonite and diamond. It detects diamond and one has to be sure the fingers are well on the plate to separate it from white sapphire and diamond . But try as i might it did not separate moissonite from Diamond. Worked with all the less hard colored stones. This price is exceptional and fortunately moissonite is much more Dear than CZ or synthetic rutile. Howeveer for bigger stone this is not the best diamond tester. One has to have one that can separate Moissonite. Unless of course one has a polariscope as moissonite is doubly refractive.

I buy a lot of jewelry on auction sites. This has really come in handy for making sure of the stones. It was a little difficult to use in the beginning but it does get easier with practice.. I would recommend this to anyone who buys their jewelry from auction sites..

This tester verifies whether or a not a diamond is real based on its thermal qualities. A small probe contacts the diamond and then LED lights let you know if its a fake or not. The device seems to be accurate as I tested it with both real and zirconians. It weas correct 100% of the time. These testers normally go for $100. This one was less then $15. Great buy.

This is a handy little tester. A bit complicated as you have to set to the size of the stone being tested. Accuracy has been about 8 of 10. Worth the money. Lightweight so you can carry with you. Just don't have cream on your hands when you test and make sure your hands are not cold or dry. It does affect the reading on the metal plate that you have to be touching to test. Over-all, a great item and worth the small price.

Didn't work right out of the box. Gave the same reading for diamonds and Swarovski crystals. Returned it for refund.

TIPS BEFORE BUYING:
This tester only takes a single 9-volt battery, but it is not included. So make sure you have one prepared, especially if you are buying this and you want to test a diamond immediately upon the tester's arrival. I wasted $5 on a single battery via Amazon, only to realize I had one in my desk drawer the entire time. I also noticed that the Dollar Tree sells 9 volts for $1 each. (I make these stupid mistakes so you don't have to, ladies and gentlemen.)

Also, make sure you take the rubber stopper off before testing. This may sound stupidly obvious to a lot of people, but it was not for me. My mom tried testing diamonds with the stopper still on, and it gave false positives on stones I KNEW were fake, but once the rubber stopper was off, it gave accurate readings.

As a complete and total beginner, it was also difficult for me to figure out what size a stone is supposed to be. If you are having the same problem, estimate and adjust to various levels. If it is fake, it will not beep regardless of what level you try it on, but if you suspect it may be real, it's worth trying at each level.

There are videos on YouTube showing this tester, and I recommend that you go find some of them, because watching a real, live person use the tester is beneficial to helping your decision on whether to buy this or not.

Overall, if you have a diamond you think may be real, I think this is worth investing in, if only to save yourself the embarrassment of going all the way to a diamond dealer only to find out you really have a cubic zircon. If the tester beeps that "yes", it is a diamond, that's great, and you should take it to somewhere that is GIA certified.
