The Short Answer:
is open to a great deal of interpretation. What one grading lab considers as a VS 2 might be called a Si
1 by a stricter grading laboratory. We
only sell diamonds graded by either AGS or GIA as they are Non-Profit,
Independent Grading laboratories. We
find their grading is accurate, consistent, and strict.
for diamonds is performed UNDER 10x MAGNIFICATION by a MICROSCOPE.
The clarity grades for diamonds are as follows:
1: Very Very Small
VVS 2: Very Very Small Inclusion(s)
1: Very Small
VS 2: Very Small
Si 2: Small Inclusion(s)
opinion on Clarity & what the majority of our customers have found.
VVS 1: Very Very Small Inclusion(s) VVS 2: Very Very Small Inclusion(s)
the customer who wants the absolute finest quality possible no matter
what. Although they know that
they may see Zero difference between a VVS 1 and a Si 2 to the naked eye,
they need to know deep down that they have given their loved ones the most
exceptionally pure diamond possible.
VS 1: Very Small Inclusion(s) VS 2: Very Small Inclusion(s)
of the customers in this range have seen other Non-GIA or Non-AGS graded
diamonds riddled with inclusions that were presented as Si 1 or Si 2.
The term ‘small inclusion’ does not sit well and they generally
want to move up into the VS range to make sure that they are secure with
the inclusions in the diamond and never have to think twice about them.
For larger sized diamonds over 2.50ct, VS Clarity is a more
Si 1: Small Inclusion(s) Si 2: Small Inclusion(s)
Depending on the size of diamond, this clarity range can offer great
value. Going into the Si
range of diamonds allows customers to increase the size of the diamond
without compromising the visible quality of the diamond.
With diamonds are over 1 carat, the relative size of the inclusions
in a Si 2 Clarity grade diamond can start to become visible so we find
that the best value is for stones of Si 1 Clarity Grade with Si 2 being a
borderline area. For stones
under .75ct Si 1 & Si 2 Clarity is definitely good value.
Clarity Factors determine the overall impact that an individual clarity
characteristic has on a stones appearance and grade. Those factors
Size Number Position Nature Relief (Contrast)
a lot to do with how easy it is to see a clarity characteristic.
Generally, the larger and more visible a clarity characteristic is, the
lower the diamond's clarity grade will be. In addition to
affe3ctiing the grade, large inclusions might also threaten a diamond's
durability. In a diamond with inclusions of different sizes,
one or two of the larger inclusions usually establish the grade if there
are also smaller inclusions, they seldom affect the clarity grade.
clarity characteristics can mean a lower grade, but grades are normally
set by how readily you can see the characteristics, not by counting them.
For example, a diamond with a number of minute, pinpoints can still
qualify as VVS. On the other hand a single large, dark, or centrally
located included crystal could drop the grade into VS, SI, or even I
are most visible when they're directly under the table. Inclusions
under the crown facets or near the girdle are usually more difficult to
see-that's why you have to examine the stone from several angles to find
all of its characteristics. The worst location for an inclusion is
where it becomes a reflector. If it lies under the table and near
the pavilion, the pavilion facets can act as mirrors and reflect multiple
images of the inclusion. This can have a major effect on the grade
if the reflections are visible in the face up position. The position
of potentially damaging inclusions, such as feathers, large knots, and
included crystals can also be significant. For example, a feather
might get bigger. Normally, feathers won't grow during ordinary wear, and
the mounting protects those that reach the pavilion, but feathers
that extend to the girdle or crown-the exposed parts of the stone-might
grow if the diamond strikes something hard enough. A central
location increases an inclusions impact on a diamond's clarity grade.
Inclusions located directly under the table affect the clarity grade of a
diamond more than those located on the backside of the stone or under the
nature, or type, of a clarity characteristic tells you whether it's an
inclusion or a blemish and if it poses any risk to the stone. Most
characteristics don't. Generally, if a stone has durability
problems, it doesn't survive the friction and pressure of the cutting
process. The effect of an inclusion on durability is determined by
its size and location. For example, a large feather that reaches the
crown poses a durability risk, but a small one probably doesn't.
an inclusion has the potential to cause damage to a stone, it CAN affect
the grade, but this is RARE, and usually applies only to included
diamonds. According to GIA, the grader probably would NOT lower the
grade of a stone on this basis alone.
5. Color or Relief
relief can affect the visibility of a characteristic as much as its size
does. Generally, the more an inclusion differs in color from its
host, the more obvious it is. Relief is the contrast between the
inclusion and the stone. The greater the relief, the more it will
affect the clarity grade. Although, most diamond inclusions
are white or colorless, some are black, brown, dark red, or on the rare
occasion, Green. Since colored inclusions are easier to see, they
might lower the grade more than a colorless inclusion. A black
pinpoint might be an exception-it's often more difficult to see than a
GIA's Guide to different types of inclusions and how they might appear on
a diamond's grading certificate.
A brief description of the inclusions is below.
Internal Characteristic Definitions (red)
Tiny Opening/hole accompanied by tiny, root-like feathers
An opening created when a crystal is pulled out, or when a feather breaks
Chip: A rounded, shallow opening on a facet junction (usually on the girdle
A break that occurs along a plane of atomic weakness
Cloud: A hazy or milky area made up of a number of very small inclusions
A crystal totally enclosed within the stone
A separation or break that reaches the surface
a small area of concentrated crystal structure distortion, usually with a
pinpoint-like or thread like appearance
A natural that dips below the diamond's surface
The appearance of faint lines or streaks against a transparent background
Knot: A diamond crystal that reaches the surface
A long thin included crystal that looks like a tiny rod
a very small included crystal
Flat or ribbon-like cloudy area produced by crystal structure distortion
External Characteristics (Green)
Tiny nicks along the facet junctions producing white fuzzy lines instead
of sharp facet edges
Part of the original rough diamond's surface
Nick: A small notch on the girdle or a facet edge that resembles a white dot
with no apparent depth
Pit: A tiny opening that resembles a white dot with no apparent depth
Fine parallel grooves and ridges left on a gem's facet from polishing
Whitish film on the surface of a facet from excessive heat during
A linear indentation normally seen as a fine white line, curved or
straight, with no apparent depth
