Presidium Gem Tester PGTII Test Run 

Thanks for the video, I wanted to test some gemstones I found and this video shows several gemstones hardness range.

This is on my wish list. Great video.

I just got my tester... LOVE IT!

Please how much does it cost

New sub here! 😻😻😻

Thanks! What would've happened if your diamond engagement ring was fake? JK. Thanks for the insightful video!

IT is true that IT detects gemstones without polishing precisely

And glass harness.

It makes some sound when I use it. I found a ruby while using it.
