Impact of Fluorescence in Diamonds
Fluorescence is a phenomenon that makes some diamonds appear
to change color when they are exposed to the ultraviolet
light that surrounds us every day in sunlight and in the
light produced by fluorescent light bulbs and tubes
Diamond Fluorescence Levels
Diamond grading reports tells whether or not a diamond
fluoresces, and if it does, how much—there levels are.
Diamond Fluorescence Colors
Diamond grading reports also tell us the color produced by a
diamond's fluorescence--usually blue, yellow or white.
Impact of Diamond Fluorescence
If a yellowish diamond fluoresces blue, the effect could be
strong enough to mask the yellowish tint when viewed in a
jewelry store's fluorescent lighting. You might be surprised
by the diamond's true color when you look at it at home
under different lighting.
The
reverse is true for diamonds that fluoresce yellow. They can
appear more white under incandescent lights, but acquire a
yellowish tint in ultraviolet light.
Fluorescence in Multi-Stone Rings
Most fluorescence provides a subtle effect, one that you
probably will not perceive as a true color change--just a
slight shift in tone. However, it could be enough to make a
diamond ring with multiple stones seem out of balance if
some stones fluoresce and others do not, or if they
fluoresce different colors.
Pricing for Diamonds that Fluoresce
A strong yellow fluorescence bring diamond prices down,
sometimes quite a bit, since yellowish tinted diamonds are
generally less desirable than whiter stones.
A blue fluorescence can help increase the prices of diamonds
with yellowish tones.
It's important for you to be happy with the diamonds
you buy. Ask your jeweler to show you examples of
fluorescence and try to look at diamonds in many types of
light before you make a decision, especially if you are
considering diamonds with no grading documentation.
