My best estimate is that this one will give the correct reading about 95% of the time at room temperature. To see how this compares with other "Diamond Selector II" diamond testers click here.

This really is quite good for a 'cheapie' diamond tester and definitely the best of all the Diamond Selector II models.



Exceptionally good value for a 'cheapie' diamond tester, do not confuse this with the Chinese copies (for details click here).


It only works at room temperature.
This is a diamond-only tester, it will not test Moissanite, that means that a Moissanite will show up as 'diamond' on this tester.


If you really do not want to pay much for a diamond tester, I'd recommend going for this one rather than resorting to a £20.00 diamond tester, this is good value for a 'cheapie' tester and it does work wll most of the time.
