1. Quick Test Mode Results
Stones with Red Marks = Synthetic / Lab Grown Diamond
Stones without Red Marks = Natural Diamond / Unknown Stones
Here are the Fluorescent Reference Images:
Diamond
Cubic Zirconia (CZ)
CVD Synthetic
Note: If the User still doubts determining the type of the Stones
whether the stone is Synthetic or Natural, do a Longwave Fluorescent
test using a regular UV light source. Lab-Grown Diamonds will not
fluoresce unlike about 25% to 30% of Natural Diamonds will do.
Important:
No red mark stones must compare with the given fluorescent reference
images to confirm its type.
