Detecting CZ (Cubic Zirconium) and Moissanite – in loose stones
The Sherlock Holmes can be very helpful in detecting CZ, Moissanite and diamond 
coated CZ and Moissanite in loose stones only!  
The diamond coated CZ and Moissanite show the exact same results as the 
regular non-coated CZ and Moissanite. 

From now on when we refer to CZ and 

Mossanite- we refer to both coated and non-coated CZ and Moissanite. 

 
Please carefully view the pictures in order to understand how to distinguish 
between Diamonds (Grown and Natural) and these simulants: 
 
In general, both CZ and Moissanite DO NOT SHOW FLUORESCENCE under our 
lighting. 
It is highly recommended to check loose stones with and without the bottom 
lamp covered with the black square supplied with the detector. 
 
IN ORDER TO MAKE THE FINAL DECISION YOU MUST COVER THE BOTTOM LAMP.  
 
When you see a stone that does not show fluorescence you can draw the 
conclusion that it is a SIMULANT AND NOT A DIAMOND. 
 
 
 
 

In the history of your detector we stored one picture with 6 
stones with the bottom lamp covered. 
The top 2 stones are diamonds and the 4 stones under them 
are CZ and Moissanite. Please go to the history and make sure 
you understand the results. 

 

 
 
 

The following pictures are not stored in your history and are just an 
example for your reference. You can see the difference between 
diamonds (natural and lab grown) and the CZ and Moissanite simulants 
with and without the bottom lamp covered.
