Presidium Gem & Diamond Tester

Gem Tester:

Need a Gem Tester? Do you need to know if your precious stone is a Diamond? Ruby or Garnet? Sapphire or Tanzanite? Emerald or Jadeite?

The PRESIDIUM GEM TESTER PROVIDES THE ANSWERS!

Provides a quick- easy- laboratory proven way to identify diamonds & separate the most popular coloured gemstones from one another. This valuable tool can eliminate human error when identifying precious gems.

The Presidium Gem Testers’ accurate performance is based on the fact that different gemstones conduct heat at different rates.
