The proven
YEHUDA
detection process involves illuminating the diamonds being tested using a
proprietary lighting system and software to determine their identity. This special light causes
ALL
the
diamonds being tested to emit light (fluoresce), while
SOME
diamonds will continue to emit light or
glow in the dark (phosphorescence) after our light is shut off.
UNDERSTANDING THE TEST RESULTS:
When the testing process is completed, 5 pictures will be shown:
1.
RESULT
- Default
2.
LUV
- Long UV fluorescence
3.
GLOWING
- Phosphorescence or glowing in the dark when the light is shut off
4.
COLORED
- Fluorescence or glowing when illuminated
5.
ORIGINAL
- A picture of the goods under white light
Result Picture:
It is the default picture result that you get at the end of the test.
1.
Any diamond that shines in
ONLY
blue color is a
NATURAL DIAMOND
.
2.
Any diamond that shines in
NON
blue color or is painted in red is a
LAB GROWN DIAMOND.
To fully understand the result picture please first read about all other results and then read the
explanation in the bottom.
LUV (LONG UV) PICTURE:
The long UV test result is
superior
to all other results.
If in the
RESULT
picture a diamond is determined as a lab grown diamond but in the
LUV
test it is
determined as a natural diamond-
THEN IT IS A NATURAL DIAMOND.

IMPORTANT :
To correctly identify the stones being tested, you cannot stop and make
your determination by only looking at the
RESULT
picture. You MUST
also look at the LUV picture, and then the
GLOWING
picture. In other
words, if you did not look at all 3 of these pictures you may make a wrong
determination of a stone’s identity.
PLEASE PAY ATTENTION!
During the test procedure our special light will cause all diamonds to show
fluorescence. We also test the fluorescence of the diamonds under a regular
LONG UV
light which, as you know, causes some diamonds to show fluorescence.
