Your cart is empty. A Remarkable designed Gemstone Tester with color estimator display for smoothly and seamlessly testing your Precious stone and diamond.
The SmartPro Gem-Eye I it was developed to distinguish between diamond and its other simulants using the principles of thermal conductivity. Diamonds, with their exceptional heat conductivity properties are unlike any other simulant, and are therefore not easily replicable.
The SmartPro Gem-Eye I is now equipped with a color stone estimator display to assist the user in distinguishing popular colored gemstones form each other.
The SmartPro Gem-Eye I consists of two linked thermometers: one, which is heated electronically, while the other is cooled by the gemstone being tested. The difference in temperature creates an electrical output, which is then amplified and displayed on an analog dial.
Included in package: SmartPro Gem-Eye I, Probe pen, AC adapter, User manual book, Warrantty card, Protective carry case, Probe tip oxidation sheet

DO NOT PURCHASE!! The unit that I received was completely non functional right away, it never even calibrated correctly. And now the company will not honor even a return becaise I no longer have the box, they have ZERO CUSTOMER SERVICE and they will straight up take your money and ignore you. FOUR THUMBS DOWN 👎👎👎👎

On some stones there was no reading at all. Needle just dead.

I had a different model than this one two of them actually. They didn’t work worth a damn. This one you can at least calibrate yourself. And it’s very easy. Other machine you couldn’t calibrated couldn’t do anything. So you really couldn’t trust it. You have to watch your calibration closely though it varies from each time that you turn it on. It’s a little bit of a pain but it’s better than the other other one I had. That one you could not calibrate it all. So I’m pretty happy with this machine

Gotta say...we purchased the Presidium tester and it came non calibrated and worked for about 3 days. We are now returning it. The Smartpro arrived today which we were able to test and it worked out of the box! You can see by the photo to that there is a major difference in quality and size. It also has a fantastic little manual for which the other unit does not. So, we will test with it for awhile and give it a go. I will update this review if we end up having to return it as well.

It cannot start up. The needle goes back and forth, then it powers off. Only started using on Sunday, and today is Wednesday. I am with the other 1 stars, first one was missing the instructions, and the second one does have scratches. But it appeared to be new. I changed the batteries still nothing... I think this may have been a reconditioned unit?

I read the reviews before purchasing, and decided it was still worth a try.Read the directions, all of them! Be sure to calibrate, use clean dry stones, and most importantly watch temperatures. At first the readings were wonky for the same gem. Back to the instructions…temperature! The house is cold, the stones even colder. I washed and throughly dried my hands and used them to warm gems one at a time. Spot on for every gem! I waited about a minute in between each gem.My recommendation is to pay attention to temperature, and pace for accuracy. (operator errors)I hope this review helps with your decision to buy this product.

I like this machine a lot, I use it all the time. But it's not for the novice. You need to have a good gemstone knowledge before using this. It doesn't tell you the exact gemstones and very little gemstones are listed. But if you know the hardness of the gemstones or use a gemstone book. You can definitely tell the difference of the gemstones. It can tell you the difference of Blue Topaz and Aquamarine. The difference of Rhodolite garnet Pink tourmaline and Pink Spinel. Just because I know the hardness. Just like any tools you need to know what you're doing with it.

I own a jewelry store and use it to test stones that I buy. I also use it to test for the customers. I like how easy it is to use. It does need to be calibrated with each use, but that is not too much of a big deal once you get use to it.
