ACCORDING TO THE SCIENCE KNOWN TODAY:
• If a diamond shines in blue in the
LONG UV
test results, it is a
100% NATURAL
diamond.
• If a diamond shines very strongly in a non-blue color in the
LUV TEST
- it is a
natural diamond as well.
•
If it shines in very light non blue color – it may be a natural diamond OR a lab grown diamond.
In this case the
LUV TEST
did not help us.
If a diamond was determined to be a natural diamond at the long UV test, it is 100% natural diamond!
Even if it gave a lab grown diamond result in the RESULT picture. This means that when you get a lab
grown diamond test result –
YOU ARE NOT DONE
. It is therefore critical that
YOU ALWAYS CHECK
THE LONG UV PICTURE TO MAKE YOUR FINAL DETERMINATION.
GLOWING PICTURE
:
Some LAB GROWN DIAMONDS show phosphorescence. (Emit light “glow” after the light source is
shut off.) If a diamond shines after the light is shut off – it is a lab grown diamond.
COLORED PICTURE:
When our proprietary lamp emits light on the diamonds, they fluoresce in different colors.
ORIGINAL PICTURE:
This is the untouched picture of the diamonds and jewelry that you are testing.
RESULT PICTURE:
This is the default picture that you see when the test has been completed. It is a combination of the
COLORED picture and the GLOWING picture.
• If the diamond fluoresces
100% BLUE
- it is always a
NATURAL
diamond.
• If the diamond fluoresces in any other color but blue, and/or is painted in red -
it is a
LAB GROWN
diamond.
• If the diamond is painted in red, even if the diamond fluoresces in blue,
it is a
LAB GROWN
diamond.
To simplify this for you, our software identifies the diamonds that glow in the dark or show
phosphorescence, and paints them in a distinctive bright red color in the
RESULT
picture.
Even though our software paints these diamonds red in the
RESULT
picture, sometimes the painting
is too strong or very light. We suggest to always go to the
GLOWING
picture to understand which
diamonds glow in the dark (show phosphorescence). For your convenience, at the bottom of the
RESULT picture you can change the amount of red painting by pressing the sensitivity buttons.
In order to be more accurate and reduce the false positive rate, you
MUST
always also look at the
LUV
and
GLOWING
pictures before making your final determination.
NOTE: BLACK IS NOT CONSIDERED A COLOR.
