What is fluorescence in a diamond?
In diamonds, fluorescence is observed when the diamond is
exposed to invisible ultraviolet rays. (Such as the lighting frequently seen in
dance clubs).Under normal lighting conditions, a diamond’s fluorescence is not
detectable to the eye. However, if a
diamonds naturally fluorescent, it will
emit a soft colored glow when viewed in ultraviolet light. Fluorescence is not dangerous to the diamond
or the wearer, nor does it compromise the diamonds structural integrity. It is simply a
fascinating quality that occurs naturally in some diamonds.
Do all diamond fluoresce in the same
way?
No. Some do not
fluoresce at all. On diamond grading reports,
non-fluorescent diamonds are described as “none.” Diamonds that do exhibit some fluorescence
can vary from faint, medium blue, strong blue to very strong blue.
How many diamonds fluorescence?
About 1/3 of all diamonds fluorescence. You can find out if your diamond is
fluorescent by holding it under a black light.
It will give off a blue color if it does have fluorescence. Blue is not the only color that a diamond can
exhibit but it is the most popular. Green, yellow, orange or red are also
colors you may see.
Good or Bad?
A diamond
with a color lower then H with a medium fluorescence can actually make the
stone look whiter, but a diamond with strong or very strong fluorescence tho can
give the diamond a milky or hazy look.
Therefore, a diamond with faint to medium blue can actually enhance some
diamonds.
Does fluorescence effect a diamond’s
price?
Fluorescence may cause you to pay a little more (0-2%) when
it comes to diamonds in the H-M color
range while in the D-G color range a diamond will actually cost you a little
less (0-15%).
Have a little fun!
Next time you
are at a night club check out everyone’s rings you might be surprised at how
many are glowing :-)
