Works really nice & easy, detecting real diamonds. I use it a lot and appreciate it's simplicity & accuracy. Price is more than fair. Won't differentiate between lab & natural diamonds but, any jewelry more than a couple years old is almost certain to have the natural (more valuable) diamonds. Color & clarity is also something not measured by this device. Still, very pleased with this piece of equipment!
A happy buyer!

My very first diamond tester and I knew I didn't want to buy cheap ones. I rather buy from the brand I trust. Very easy to use. Click the button to turn it on, flashing light for less than a minute. Once the light is solid, you can test out your diamonds. Comes with a charging cord but not sure how to find once charging is full since there is no indication.

We don't have many choices in the jewelry industry for diamond testers. So we have to get something that's out there. Presidium is the most popular tester for diamonds. This tester works great so far. One helpful hint for small diamonds. Make sure you don't hit any metal when testing because it will beep as a diamond. Wear magnifying glasses if you have to. Go straight down on the diamond and don't slant the pen. It should work fine.

Worked great for about 6 months. then will not hold a charge more than 2 min. AVOID THIS ITEM. Not worth the cost. Then you're stuck with junk.

Nice product. I like the thin tip. Able to test smaller stones in really tight, recessed spaces easily. Been using it daily for several months on the original batteries. Start time is about a minute or less. Would order it again if needed.

This works like a charm. I found out the diamond earrings that I bought at Kohls are not diamond, though. That makes me mad. But all of my other diamond register perfectly. It's very easy to use.
