Accuracy Jewelry-Diamond Tester Pen Professional Jewelry Diamond Tester Tool

Great tested it on Dimond, moissanite and cubic zirconia. Works great can definitely identify real stones.

I see these used on social media all the time. I had no idea the needle had a cap over it. It wasn’t very clear in the instructions. It works really well.

I found what I thought was a diamond laying on the ground in the parking lot at a local Walmart. It captured the light just right, so even though it was tiny, I was still able to see it. It cut glass, but lab created diamonds can also cut glass. I was going to take it to one of our local jewelers to look at it and see if it was real, however I knew they could probably get over on me, so I just bought this for myself. It's good to have, especially when buying 2nd hand jewelry that people claim are real - this is a good tool to carry so you can verify before getting scammed. I tried it on one of the rings in my bridal set, it identified it was a genuine diamond (listed as this as well), and I tried another ring, swarovsky crystal, it didn't light up. I tried the "diamond" I found in the parking lot and it was a very low reading on the meter, meaning it was not a genuine diamond. Broke my heart but I'm glad I was able to check and get an answer! I recommend this tool, especially if you're interested in gems and such.

It worked perfect! It can definitely identify real and fake diamonds, as well as sapphires. Really handy tool to have.

From I buy this product it never work the battery I put in it are all new batteries just waste of money
