Review on VCCA High Accuracy Jewelry Diamond Tester II: The Ultimate Thermal Conductivity Meter for Novice and Expert Gemstone Selection by Gina Cravalho

Revainrating 5 out of 5

Cheap and bulky but works

Awkward to use - you have to wait for it to warm up, then adjust the sensitivity and hold it properly to get a reading. But it was cheap and great for my use when testing sapphire watches.

Pros
  • Great design
Cons
  • Sad hardware
