Another vital grading characteristic in diamonds is their clarity.
This refers to the number, position and size of the inclusions that
occur naturally inside diamonds. The fewer and less obvious the inclusions,
the more valuable the diamond. Below is
the clarity grading scale that has been established by the world’s
foremost authority on diamonds, the Gemological Institute of America
(GIA). Note: Diamonds are shown under 10X magnification):
F - Flawless. The diamond shows no inclusions
or blemishes of any sort under 10X magnification when observed by
an experienced grader. Note: Truly flawless or internally flawless
(F or IF on the GIA’s grading scale) diamonds are extremely rare.
IF - Internally Flawless. The diamond
has no inclusions when examined by an experienced grader using 10X
magnification, but will have some minor blemishes.
VVS1, VVS2 - Very, Very slightly included.
The diamond contains minute inclusions that are difficult even for
experienced graders to see under 10X magnification.
VS1, VS2 - Very slightly included. The
diamond contains minute inclusions such as small crystals, clouds
or feathers when observed with effort under 10X magnification.
SI1, SI2 - Slightly included. The diamond
contains inclusions (clouds, included crystals, knots, cavities, and
feathers) that are noticeable to an experienced grader under 10X magnification.
I1, I2, I3 - Included.The diamond contains
inclusions (possibly large feathers or large included crystals) that
are obvious under 10X magnification and may affect transparency and
brilliance.
It is these inclusions or blemishes that give each
diamond its own unique fingerprint, making your particular diamond
truly yours. In fact, the independent grading report that comes with
every diamond we sell will show a diagram indicting any characteristic
your diamond, indicating any blemishes your diamond may have, as well
as their location. The most important thing to remember when it comes
to clarity is that a diamond’s inclusions should not be noticeable
to the naked eye, nor should they be so excessive that they affect
the diamond’s durability . |
