Summary

  • Tests for diamond, Moissanite and white sapphire 
  • The top of the tester lights up Dia, Mois, Saph, Metal 
  • To see an article all about diamond testing click here. 
  • Guarantee, 1 year.

The new very-low-conductivity Moissanites are difficult to test. Gemoro say this is, "the only tester that can correctly identify the new Forever One colorless mossanite. All other testers will incorrectly identify it." However, a) this only refers to the Forever One brand of Moissanite, and that has been around for a few years now. b) we have clarified this with them and they remind us (which we know!) that no tester is ever 'guaranteed' to give a correct reading. c) our other manufacturers regularly 'tweak' the sensitivity of their testers to keep up with the very-low-conductivity Moissanites coming onto the market. 

Operation

Switch on, wait for it to warm up, place probe on stone, see if it lights up Dia, Mois, Saph, Metal ('metal' means  you missed the stone and touched the setting), 

Technical

PHYSICAL

Dimensions: 7"X1½"X¾" 155X38X20mm

Weight: 95g

Tip: can test stones down to 0.02ct (2pt) in size. 

Operating temperature: between 18 and 27 degrees C (64 to 81 degrees F). 

RESPONSE TIME

Warm-up time when switched on: 20 to 30 seconds

Testing: result in 1 or 2 seconds

Warm-up time between tests: 2 or 3 seconds

UV

Whilst in operation the UV light is always on. 

POWER 

Rechargeable. Charge by plugging the USB cable into a USB power supply (e.g. a computer or a USB mains adaptor).  

You can also use it while the USB cable is plugged into a power supply, in which case it won't use the batteries. 

Battery life: no idea. Since rechargeable batteries aren't as powerful as non-rechargeable and the UV light stays on and there's a power on light- we'd guess a few dozen tests per charge.

Low-battery indicator: none, when it fails to warm up, it needs a new battery

Auto-shut-off: it turns itself off if not used for five minutes.

ACCESSORIES / PRESENTATION 

  • zip-case
  • stone-holder
  • cloth to clean the stone (described as a 'diamond testing cloth')
  • instruction booklet

RELIABILITY

New product as of June 2024, too soon to say.

Limitations

  • Will not test fancy-coloured stones
  • You can change the rechargeable batteries for ordinary batteries (3 of AAA) but the battery compartment cover is nearly impossible to remove
  • Synthetic diamonds (not to be confused with simulants!) usually register as Moissanite
  • the Moissanite test is very sensitive, both stone and test-tip must be 100% clean and grease-free, you will cover the stone in a layer of grease simply by touching it with your finger (this is a 'limitation' for anyone expecting a quick-easy-accurate test).   

Disclaimer

All testers must be used in conjunction with the user's skill, knowledge and experience. Under no circumstances shall QUICKTEST be liable for direct or indirect loss sustained in connection with any item. Nothing is 100% accurate, you must understand the limitations of any tester. We also suggest you regularly test known samples to check for any obvious faults. 

Alternatives

Please note, none of the testers listed below 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).

[1] All testers test loose stones but not all can test mounted (set in jewellery) stones.

[2] The probe / analogue meter will test mounted stones, the digital meter will only test loose stones.

[3] The probe / analogue meter: 17 stones; the digital meter: 40 stones.

[4] Skill and practice is required to use an optical refractometer, instructions are not included, see any textbook about gemmology…or the internet.
