Summary

If you have a diamond tester (a diamond-only tester) it will register 'diamond' on Moissanite (a manmade stone). 

Of course, the 'good' testers ("multi-testers") will test for both diamond and Moissanite - but if you only have a simple diamond-only tester, you will need a Moissanite tester to see if the stone might be Moissasnite. 

This tester cannot be used on its own, it is to check for Moissanite after it has tested as 'diamond' on a simple diamond-only tester. If you do not already have a diamond tester, do not buy this item.

Accuracy / Guarantee

Generally, Moissanite is electrically conductive (but only very very slightly); generally, diamonds are not.

But there are exceptions.

A tiny proportion of diamonds are electrically conductive and will read "Moissanite" on this tester.

They are now making Moissanites (Moissanite is a manmade stone) which have very low electrical conductivity and register "Diamond" on most testers, including this Moissanite tester. 

Therefore, the result on this Moissanite tester has a high probability of being correct but is not guaranteed.

The best 'low cost' multi tester for reliability in testing Moissanite is the Multi-exp; the  absolute best (and most reliable) is the SAM

Our 1-year guarantee is against complete failure, no tester give you guaranteed 100% accuracy; generally, the more you pay the better the accuracy.

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 you buy. We also suggest you regularly test known samples to check for any obvious faults.

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).

[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.  

 

QUESTIONS & ANSWERS

Ask a Question
  • Hello, What is the guarantee period for this tester. Thank You. Tim

    One year.

  • Can you test for diamonds and semiprecious stones?

    No. This is a Moissanite tester.

    If you have a cheap diamond tester, Moissanite will show up as 'diamond' and so you will need a special tester (e.g. this one) to see if it is Moissanite.

    For testing diamonds see our guide to diamond testers.

    Quite separately, for testing gemstones see our guide to electronic gemstone testers.
