This is the absolute-best multi-tester for non-diamond / diamond / Moissanite

  • this is the only tester that works on the new (low-conductivity) Moissanites that show up as 'diamond' on most testers (and there is no UV light to help with "difficult" stones - it just works!)
  • fastest response time (test-result in 1 second)
  • left-handed or right-handed use
  • thinnest probe (0.45mm) tests stones as small as 0.01 carat (1 point)
  • can be used with batteries or USB power
  • in its case it's smaller an neater than other diamond testers.
  • one year guarantee

See our Guide to buying diamond testers.


Turn it on, wait 10 seconds for it to warm up, place the probe in the centre of the stone, large clear LED bars indicate: Low Batt, Metal alert (meaning you've missed the stone and touched the setting), Simulant (i.e. not diamond), Moissanite,, Diamond, Touched metal (i.e. you missed the stone and tested the setting).

Summary of instructions (you are meant to download the full instruction booklet).


I haven't tested thousands of stones but I estimate that this tester will give the correct result close to 100% of the time (97%? 98%?) - there is no tester in existence that is 100%.

Developed a fault in the guarantee period (1 year): new item, not enough sold to know.
