Review: The perfect tester for us regular folks! - I love this tester and it's easy to use. I am well aware of how delicate the tester point is, so I am VERY careful with it and keep the tip cover on when not in use. This is a great item to have on hand. You can test all the gems you're unsure about... and do the same for your friends. It comes in a nice case and is easy to store. I had a tester for decades before this one, but it just tested diamonds. This one does so much more and the price is so reasonable. Treated right, you will have it for years and years. AND... it's so easy to use!
Review: Works fantastically if you know gems. - We are not new to gemstones. 25+ years experience. We usually test with refractometer, polariscope, spectroscope, etc. but this is portable and customer displayable. It came today and I tested 100 cut stones with 100% accuracy once I calibrated it and got a feel for pressure and 90* angle on the probe. It tested one of my prettiest cut garnets as glass! *^+}{^*! But I put that garnet under the refractometer and it is indeed glass. I hope I didn’t pay much for that rock. This machine tests thermal conductivity. Pretty reliable method to distinguish Glas from precious stone. But; a lot of specimen species have the same thermal conductivity. It’s really good for telling if that ruby ring is a ruby and not garnet or glass. It’s just a starting clue for identifying “what is this random gem?” It calibrates easily. The case isn’t protective enough, especially of the probe. Tools this low price won’t define lab vs natural - need a microscope and skills for that. Overall it’s a great buy at a reasonable price. You don’t become a Graduate Gemologist with one tool but it’s great for buyers, resellers, and collectors to confirm what you’ve got. Easy to use. Performs outstanding. A touch expensive for occasional use. Treat that probe gently, a new on will cost you. Read a book or two if you don’t know that amethyst and citrine are the same mineral species or that sapphire comes in colors. It doesn’t do opal or organics.

It is not as accurate as we hoped and the descriptions are not accurate if glass and all the items below it are the same reading and you have to have the batteries in it as well as being plugged in or it will not work. The point of batteries is so it can be used off site for testing items where there may not be electricity, but guess you can use a power pack. I sent pictures of the box before too, it had a small box with the items in it and then no packing to protect it, so it bounced around and had some damage, have not had long enough to know if work properly or not yet due to any damage that may of caused.
