## Customer Reviews

### ⭐⭐⭐⭐⭐ Great tools for the novice or expert jewel collector
*by L***Y on July 6, 2025*

Top notch quality, and usefulness!

### ⭐⭐⭐⭐⭐ Works flawlessly
*by H***E on September 25, 2024*

The media could not be loaded. It works exactly as intended. I tested my diamonds and I tested CZ. It recognized my diamonds and not the CZ. I haven’t tested the scale or the other items yet but I know they’ll work great when I need them. This is a great inexpensive tester, that works as intended. It is a bit loud but that’s ok. It’s just a diamond tester so it’s not going to beep just for fun lol. It’s super easy to use, and has a good nose point, to touch the stones. I would absolutely recommend this particular set. It’s worth every penny

### ⭐⭐⭐⭐ Take the cap off the diamond tester side.
*by G***A on December 17, 2023*

I was going to return this because it would either beeeep all the time at level 9 or do nothing… until I went to YouTube and watched a video. The included instructions are terrible. Search for samples on YouTube. The tester tip is covered with a plastic cap to protect it- duh- and you have to uncover it.That being said, YouTube also speaks to the unreliable testing this tester provides… so idk if it is worth it, hence the 4 star- but the fact is that it now “works as instructed” hence the 4 stars as well. I at least know it’s not a piece of plastic. Setting the initial “level” is very subjective and ca lead to inaccuracy. Hope this helps.
