Evaluating Gemstones and Gemstone
Jewelry Under The Right Lighting
In the old days, color and light were a
much simpler concept to understand.
There was natural light from the sun or
synthetic light from lamps or fire.
Nowadays there are many different
sources of light and the options seem
endless. Each light will give a
different aspect to gemstones and it is
important to find the most suitable
light in which to grade and evaluate the
stones in so that you can discover their
true properties. As well as the
countless types of light that you can
use during evaluation, it is important
to remember that a different light may
be needed for a different type of
gemstone. As well as different levels of
brightness, light gives of altering
color spectrums and in the gemstone
business, the color of light as a
function of its temperature is measured
in Kelvins (k) which is higher according
to the strength of the light and the
level of red in the spectrum.
Colored gemstones are worthless without
their color and it is very important
that their color is judged and graded
correctly before purchasing. The color
of a gemstone arises from light
interacting with the trace materials in
the stone. In order for the light to
interact with the stone, the light must
contain all the colors needed in its
spectrum. If the light source does not
contain the specific colors then they
will not be able to be seen correctly on
the gemstone.
As people are becoming more aware of how
light affects how we see gemstones,
there are more options available from
lighting stores that allow specific
lamps and bulbs to be purchased for the
use in gemstone evaluation. There is a
wide variety of lamps available now,
each with their own specific qualities
which affect how they help to view
gemstones. Incandescent lamps are not a
good choice for evaluating gemstones as
they are high up in the red color
spectrum and low in blue, this will
affect the color of the gemstone as you
view it. Fluorescent lamps are available
with a 'daylight' bulb which will
imitate natural daylight and it is a
good light for gemstone evaluation. The
newest technology for lamp bulbs are
LED, these are a great way to illuminate
gemstones as they are low wattage and
can imitate daylight in a natural way,
without using a lot of power and energy,
these lights are generally used in
display cases.
The best way to evaluate gemstones will
always be in natural daylight, this is
not always possible and with all the
altering environmental aspects that
affect it. Using lamps with specific
bulbs that will mimic daylight and can
be set to different color grades and
Kelvin strength allow evaluation to take
place in any given place and with a
higher standard for accuracy and
precision.
