Grading - Clarity
diamond's clarity grade is actually a flaw-grade and refers to the tiny
imperfections present when the stone was originally formed by nature. If
no flaws can be seen under 10X magnification, such as with a diamond
loupe, it is considered "flawless".
13 classes of flaws internal (inclusions) and external (blemishes), but
the most common are dark spots of foreign material, tiny internal cracks
called "feathers", and external nicks or chips.
diamond clarity grades are as follows:
Flawless. Cannot be seen with a 10X diamond loupe.
Internally Flawless. Has tiny nicks or scratches that can be
VVS2: Very, Very Slightly Included. Very, very difficult
for a qualified observer to see under 10X magnification.
VS2: Very Slightly Included. Very small inclusions, very
difficult to see by a qualified observer.
SI2: Slightly Included. Can be seen fairly easily by a
qualified observer with a 10X loupe, and in some cases without
I2, I3: Imperfect. Inclusions can be seen with the naked
eye, but can be desirable stones at a much lower cost if they are
brilliant and lively. Because I3 is the lowest grade used, be on the
lookout for industrial grade diamonds not suitable for jewelry that
have been classified I3.
FL and IF
diamonds are extremely scarce and expensive, so are rarely used in
jewelry. VVS stones are rare and priced at a premium, but VS diamonds
are more readily available in good color and cut. With SI and I1 stones
you find your bargains in good looking diamonds, and I2 should be the
bargain hunter's choice for earrings that cannot be viewed up close.
grades dramatically affect the value of a diamond, but down to I1 have
little effect on its beauty.
enhancement techniques are being used today and should be disclosed by
reputable jewelers. The most common are lasering to remove black
inclusions, fracture filling to hide cracks and heat or
radiation treatment to lighted or change the color.
