These HPHT and CVD lab grown 

stones show phosphorescence. 

Simulants and natural diamonds 

show NO phosphorescence 

whatsoever.

Only the natural diamond on the 

bottom right shows some blue 

fluorescence. Simulants and lab 

grown diamond will never show 

fluorescence under Long UV 

illumination.

SIMULANTS

SIMULANTS

Non-diamonds do not show fluorescence or phosphorescence at all. That means they will not emit light under our 
proprietary light or under the long UV illumination. If they show any color at all, please understand that it is only a 

REFLECTION. You can easily discern if the stone shines or just reflects some light.

The top 2 stones are moissanite.
The 2nd row of stones are CZ.

The bottom 3 stones:

- The left one is an HPHT lab grown diamond.
- The middle one is a CVD lab grown diamond.
- The right one is a natural diamond.
