## Description

Accuracy Jewelry-Diamond Tester Pen Professional Jewelry Diamond Tester Tool

## Features

- This gemstone testing equipment is not only a diamond tester, but also a multi gemstone tester. It can detect if a gemstone is real or fake, including: diamond, sapphire, ruby, crystal, agate, jadeite, and other precious stone of various sizes.
- * If the number of lights equals or exceeds 9, and it beeps, it means the diamond is true. * If the lights is about 9 and it beeps, it means the sapphire is true. * If the number is 6.5-7, it means the agate is true. * If the number is 7-8 , it means the crystal is true. * If the number is 6-7, it means the jade is true.
- Before Test: 1. Put the battery in the tester. 2. Take off the probe cap. 3. Turn on the switch. 4. Make sure only one light light up on the scale. 5. Make sure the " ready lamp" light on. 6. (If test diamond, you then need to turn on the lights number corresponding to the indoor temperature and diamond weight.). 7. (If test other gems, you'd better calibrate the probe, method: by placing the probe vertically on a glass, then adjusting the light to 5, then test the gems.)
- ★ NOTICE: * No matter what gemstone you are testing, the probe needle and the tested object must be at a 90° angle. * When testing diamond, your right index finger must keep touching the metal panel on the back of the tester, while you do not touch the panel if you test other gemstones. * Do Not test any metal. * Do Not wear glove.
- Product size: 16 * 4 * 2.2 cm. weight: 100g. Power needed: 1x 9V battery (not included). If you have any problem about the testing, please contact us, we would love to help.

### ⭐⭐⭐⭐⭐ 







  
  
    Great, but instructions could be clearly.
  

*by R***N on Reviewed in the United States on 2 February 2023*

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.

### ⭐⭐⭐⭐⭐ 







  
  
    Does the trick without having to turn down offers from a pawn shop or jewelry store
  

*by T***L on Reviewed in the United States on 9 April 2024*

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.
