Summary
Very reliable make, GemTrue. This is the latest model following on from their Diamond Plus.
Automatic display, no need to adjust the sensitivity according to the size of the stone and the temperature, three lights: Diamond (= diamond or Moissanite*) or Other (= not diamond), or Metal (= you've missed the stones and have touched the setting by accident).

Limitations
This is a diamond-only tester, it will not test Moissanite, that means Moissanite will register 'diamond' (for other models see the ALTERNATIVES tab).
A UV light serves no purpose when testing diamonds v. non-diamonds (though it does help with testing diamond v. Moissanite in the multi-testers).
Alternatives
Please note, none of these testers will distinguish natural stones from synthetic stones. "Synthetic" is a scientific term meaning 'made by man in a factory/laboratory to the same formula found in nature'. The two are usually indistinguishable, synthetic diamond is diamond (read about synthetic diamond testers and see our ARI and ARETE models).
The testers below are to distinguish diamond from non-diamond (simulant/imitation).
