Finish, Culet Size,
and Girdle Thickness:
Categories of the GIA
Diamond Cut Grading System
This booklet summarizes the relationship of Finish, Culet Size, and Girdle Thickness to
the GIA Cut Grading System for round brilliant diamonds. It is intended to help members of
the jewelry trade better understand the attributes of diamond appearance, and how those attributes
are evaluated within the GIA Cut Grading System.
In the GIA Cut Grading System for standard round brilliant
diamonds, finish (for Polish and Symmetry features) is
factored into the final overall cut grade as follows:
• To qualify for an Excellent cut grade, polish and
symmetry must be Very Good or Excellent.
• To qualify for a Very Good cut grade, both polish
and symmetry must be at least Good.
• To qualify for a Good cut grade, both polish and
symmetr
y must be at least Fair
.
• To qualify for a Fair cut grade, both polish and
symmetry must be at least Fair.
• A Poor cut grade is assigned when either polish or
symmetry is Poor.
To determine the relationship between finish and overall
cut quality, GIA conducted extensive observation testing
of numerous diamonds using standardized lighting and
viewing conditions. Observations of diamonds with
comparable proportions, but differing in their polish and
symmetry categories, were analyzed to determine the
ef
fects of finish on overall cut appearance. In this way
,
GIA found that a one grade difference between the other
aspects of a diamond’s cut grade and its polish and
symmetry assessments did not significantly lower a
trained observer
’s assessment of face-up appearance, and
could not be discerned reliably with the unaided eye—
e.g., polish and/or symmetry descriptions of
V
ery Good
did not cause observers to lower their assessment of a
diamond that would otherwise receive an overall cut
grade of Excellent.

Finish—Polish and Symmetry

Categories of the GIA Diamond Cut Grading System
In the GIA Cut Grading System “polish” refers to the
quality of a diamond’s surface condition as a result of the
polishing process or to blemishes created after the cutting
process, often referred to as “wear and tear.” Polish features
are located on the surface and do not visibly penetrate into
the diamond as seen at 10X magnification. Polish is
assessed on a scale consisting of Excellent, Very Good,
Good, Fair, and Poor. A number of features are considered
in the evaluation of polish. GIA Laboratory graders
consider the amount and visibility of the polish features
present. The general appearances of GIA’s five polish
categories and various polish features are described below.
As with all other aspects of diamond grading, standard
methodology and a controlled environment are used to
evaluate polish consistently. The following steps are
performed at 10X magnification with either a fully corrected
loupe or a gemological microscope under darkfield illumina-
tion to assess polish (the final result in the GIA Laboratory
is an objective consensus of independent grader opinions):
(1) The diamond is first examined face-up, girdle-to-girdle
to gain an initial impression of the polish; (2) The diamond
is then examined one section at a time, through both the
crown and pavilion, to locate and identify the specific
polish features present; (3) The diamond is again examined
face-up, girdle-to-girdle, and this time viewed in at least
four different positions with a loupe; some features may be
more or less apparent depending on the orientation of the
diamond; (4) A verbal polish description is assigned that
considers the diamond’s overall face-up appearance as well
as polish features seen in any view. Emphasis is placed on
the diamond’s face-up appearance as seen with a 10X loupe.
Polish
CATEGORIES
Excellent: ranges from no polish features to a few minute features that can be viewed
face-up with difficulty at 10X magnification.
Some typical features that would be allowed in the Excellent category include a few pits or
nicks, a small area with faint transparent polish lines, or negligible scratches or abrasion.
* Although a diamond with a few minute polish features might qualify for the Excellent polish
category, the same diamond could not qualify for a Flawless clarity grade. Only diamonds
with no polish features visible at 10X magnification qualify for a Flawless clarity grade.
Very Good: minor polish features are seen face-up at 10X magnification.
Some typical features that would establish a Very Good category include several pits or nicks,
a few small areas of abrasion, a limited extent of moderate transparent polish lines, a small
area with faint white polish lines, several faint scratches or a few heavier white scratches, faint
lizard skin, or a small area of very faint burn marking.
Good: noticeable polish features are seen face-up at 10X magnification. The luster of the
diamond may be affected when viewed with the unaided eye.
Some typical features that would est
ablish a Good category include moderate to heavy trans-
parent polish lines, white polish lines, many heavy scratc
hes, lizard skin or burn marks.
Fair: obvious heavy polish features are seen face-up at 10X magnification. The luster of the
diamond is affected when viewed with the unaided eye.
Some typical features that would establish a Fair category include heavy white polish lines or
burned facets over most of the crown or pavilion.
P
oor:

Categories of the GIA Diamond Cut Grading System
In the GIA Cut Grading System, “symmetry” refers to
the exactness of the shape of a diamond and the sym-
metrical arrangement and even placement of the facets.
As with polish, a number of features are considered in
the evaluation of symmetry; these are defined and
illustrated below.
Symmetry features can be subdivided into two types:
proportion-related and facet-related. Due to a polished
diamond’s three-dimensional nature, the presence of one
symmetry feature may be linked to others. GIA
Laboratory graders consider the extent and visual appear-
ance of any symmetry features present.
The general appearances of GIA’s five symmetry
categories are described below. The following steps are
performed at 10X magnification with either a fully
corrected loupe or gemological microscope under
darkfield illumination to determine the symmetry of a
polished diamond (the final result is an objective
consensus of independent grader opinions): (1) The
diamond is first examined face-up, girdle-to-girdle in
order to gain an initial impression of the symmetry; (2)
The diamond is then rotated in profile view to reveal any
symmetry features that are best seen in this position —
such as non-pointing, misalignment, wavy girdle, girdle
thickness variation, table and girdle not parallel, crown
Symmetry
CATEGORIES
Excellent: ranges from no symmetry features to minute symmetry features that can be
viewed face-up with difficulty at 10X magnification.
Some typical features that would be allowed in the Excellent category include misaligned,
misshapen, non-pointed, or extra facets that are barely visible.
Very Good: minor symmetry features are seen face-up at 10X magnification.
Some typical features that would establish a Very Good category include slight table or culet
off-center, a slightly out-of-round outline, and/or minor misshapen, non-pointed or extra facets.
Good: noticeable symmetry features are seen face-up at 10X magnification. The diamond’s
overall appearance may be affected when viewed with the unaided eye.
Typical features that would establish a Good category include any proportion feature that is
noticeable: table or culet off-center, out-of-round outline, wavy girdle, table and girdle not
parallel, girdle thickness variation, crown or pavilion angle variation, and/or many noticeable
misshapen, mis
aligned, non-pointed, or extra facets.
Fair: obvious symmetry features are seen face-up at 10X magnification. The diamond’s
overall appearance is often affected when viewed with the unaided eye.
T

diamond is again examined face-up, girdle-to-girdle, and
this time viewed in at least four different positions with a
loupe; some features may be more or less apparent
depending on the orientation of the diamond; (4) The
grader checks the values of the optically measured
symmetry features to evaluate the degree of misalignment,
especially culet off-center, table off-center, and out-of-
round; (5) A verbal symmetry description is assigned that
considers the diamond’s face-up appearance as well as
symmetry features seen in profile view. Emphasis is
placed on the diamond’s face-up appearance as seen
with a 10X loupe.
While this chart focuses on symmetry evaluation as part
of the GIA Cut Grading System for standard round
brilliant diamonds, most of the criteria apply similarly to
fancy shapes with the addition of some specific guidelines
in regard to shape and lines of symmetry.
Variations in crown height and/or pavilion depth result
from one or more of the following deviations: wavy
girdle, table and girdle not parallel, crown angle varia-

variation.

Finish, Culet Size, and Girdle Thickness
The culet is a polished facet placed parallel to the table, the
purpose of which is to prevent damage to the point. Culet
size is an important element in GIA’s Cut Grading System,
as it can affect evaluations of the face-up appearance.
To determine the significance of culet size, GIA
researchers used computer modeling and visual obser-
vations to examine the effects of these proportions on
face-up appearance — for example, eye-visible culets
that may disrupt the face-up pattern.
In the GIA Laboratory, graders first assess culet size face-
up, looking through the table facet at 10X magnification.
In GIA’s International Diamond Grading System™, culet
size is described as None, Very Small, Small, Medium,
Slightly Lar
ge, Large, Very Large, or Extremely Large. If
there is no culet facet the size is reported as None. When
all eight mains meet each other, it may be referred to as
“pointed.” If the culet is at more than a slight angle to the
table facet, the size is also reported as None, as it is no
longer considered a culet but an extra facet.
Culet size can be measured through the use of a non-
contact optical measuring device or with the GIA
Multi-Purpose Gemological Reticule and a standard
gemological microscope. These measurements can be
expressed as a percentage relative to the average
diameter of the diamond, which graders may use as a
guide when making visual assessments. Because
measured results are susceptible to the variability
inherent in measurement device tolerances and clarity
characteristics as well as irregularities in shape or angle,
the final call is determined by visual observation. To
support their visual assessment of culet size, GIA
Laboratory graders use photographic references. The
accompanying chart provides definitions and typical
examples for each description and their relationship to
the calculated culet-size percentages.

Culet size percentages shown here represent typical values (not the highest or lowest point) for culets that are octagonal in shape. None,
Very Small, and Small are best evaluated visually since these fine measurements are more susceptible to measurement tolerances and the
presence of clarity characteristics. For these same reasons, in addition to the fact that the culet may be irregular or not parallel to the table,
all assessments must be verified visually.
The culet is a facet placed at the tip of the pavilion where the mains meet to
reduce the risk of damage on loose diamonds. Although the definition of
culet is limited to the facet located at the bottom of the pavilion, this term is
commonly used to ref
er to this area in general.

The girdle is a narrow section separating the crown from
the pavilion and functions as the diamond’s setting edge,
reducing the risk of damage when sufficiently thick. The
girdle of a standard round brilliant diamond is scalloped
and consists of 16 “valley” and 16 “hill” positions created
by the final brillianteering (cutting). Both the average
girdle thickness percentage and the minimum/maximum
verbal descriptions are important elements in the GIA Cut
Grading System. A thick girdle can contribute toward a
heavier diamond than its face-up appearance warrants, and
a thin girdle can increase the risk of damage such as
chipping. GIA Laboratory graders visually assess girdle
thickness at 10X magnification with the diamond in profile
view
, and consider each of the 16 valley positions and their
thicknesses relative to the diameter of the diamond.
The average girdle thickness is measured strictly by an
optical device and its percentage calculated using the
provided formula. In contrast, the minimum and
maximum verbal descriptions rely on the judgment of
GIA Laboratory graders at 10X magnification. Girdle
thickness is assessed as a range from the thinnest to
thickest valley positions; these valley positions – or thin
areas – are located where the upper and lower half facets
come closest to meeting. Girdle thickness is verbally
described as Extremely Thin, Very Thin, Thin, Medium,
Slightly Thick,
Thick, Very Thick, and Extremely Thick.
Minimum and maximum girdle thickness can be
measured through the use of a non-contact optical
measuring device or with the GIA
Multi-Purpose
Gemological Reticule and a standard gemological micro-
scope.
These measurements can be expressed as a
percentage relative to the average diameter of the
diamond, which graders may use as a guide when making
visual assessments. Girdle thickness assessments (min.
and max.) must continue to rely on visual observations
because measured results are susceptible to the variability
inherent in measurement device tolerances and clarity
characteristics, as well as irregularities in shape or angle.
This is especially true when distinguishing between
extremely thin and very thin girdles.
An extra facet, natural, chip, cavity, or indented natural
located at the girdle edge can narrow the girdle, in which
case the remaining area is considered in the thickness
assessment. If a “knife-edge” is created, the girdle thick-
ness is reported as Extremely Thin. When a chip, cavity,
or indented natural breaks through the girdle onto the
crown and pavilion, the effect on the girdle thickness is
not considered in the assessment.To support their visual
assessment of girdle thickness, GIA Laboratory graders
use photographic references as well as the girdle thick-
ness percentages of the “valley” positions. A description
of the girdle thickness is assigned based on the visual
appearance at 10X magnification. When both the thinnest
and thickest results fall in the same category, a single
description is reported, such as Very Thin. More often,
however, thickness is reported as a range from the
thinnest to thickest valley areas, e.g., Very Thin to
Medium. Variation in girdle thickness is also accounted
for in the assessment of the diamond’s symmetry or in
evaluation of painting or digging out (see below). The
girdle’s condition may be bruted — the surface produced
by the process used to shape the round diamond — or it
may be polished or faceted. The girdle’s thickness is
assessed the same, regardless of its condition. The
examples shown illustrate approximate sizes for visual
comparison and are not boundaries.

Girdle thickness percentages shown here represent typical values (not the highest or lowest point) for symmetrical diamonds with evenly
scalloped girdles. Extremely Thin and Very Thin are best evaluated visually since these fine measurements are more susceptible to
measurement tolerances in the presence of clarity characteristics. For these same reasons, in addition to the fact that the girdle may be
irregular or not perpendicular to the table, all assessments must be verified visually.
An extra facet on the pavilion side of this diamond
narrows the girdle at a “hill” position. The girdle thickness
in this example would be reported as a range from Thin —
at the location of the extra facet — to Slightly Thick — the
thickest “valley” position present.

Painting and Digging Out: A Type of Girdle Thickness Variation
Understanding Painting and Digging Out
While we illustrate here how to observe this visually,
GIA calculates the extent of painting and digging out
from the three-dimensional model produced by the non-
contact measuring systems used to find a diamond’s
proportions and angles.
Visual Cues at the Girdle
In a diamond with a normal girdle, the girdle thickness at
the points where the bezel facets meet the pavilion mains
is roughly equal to the girdle thickness at the points
where the center junctions of the upper half facets meet
the center junctions of the lower half facets. With all of
these hill positions being relatively equal, there’s fairly
even scalloping of the girdle all around the diamond.
During fashioning, the polisher uses techniques called
“painting” and “digging out” to change the relative
positions of the upper and/or lower half facets. As a
result, the girdle edge at the half-facet junctions can
become thicker or thinner relative to the girdle edge at
the bezel-main junctions and their relative angles change.
Both techniques can be used to maximize weight yield,
especially if a small difference can lift a diamond beyond
an important weight threshold, such as the half-carat,
one-carat or two-carat levels. Digging is also used to
remove clarity characteristics located near the girdle.
Moderate to strong painting or digging out will change
the face-up appearance of a diamond, even if all of the
facets are arranged symmetrically and the proportions fall
within traditional ranges for better looking diamonds.
Painting
When painting, the cutter tilts the upper or lower half
facets toward the bezel facets or pavilion mains. In a
diamond with a painted girdle, the thickness of the points
where the upper half facet junctions meet the lower half
facet junctions is greater than the girdle thickness where
the bezel facets meet the pavilion main facets.
Digging Out
Digging out is the opposite of painting.
When digging
out, the cutter tilts the upper and/or lower half facets,
away from the bezel or pavilion main facets and toward
each other. In a round brilliant with dug-out facets, the
girdle thickness at the points where the upper half facet
junctions meet the lower half facet junctions is less than
the girdle thickness at the points where the bezel facets
meet the pavilion main facets.
Impact of Painting/Digging Out in the
GIA Cut Grading System
The visual impact of painting and digging out varies with
the combination of diamond proportions in a complex
way. Among diamonds of typical proportions, GIA has
found that most people prefer diamonds that are neither
painted nor dug out beyond minimal thresholds. GIA
calculates the extent of painting or digging out from the
three-dimensional model produced by the non-contact
measuring systems used to find a diamond’s proportions
and angles. This calculation is not yet available through
Facetware. These charts are merely a guide to show the
slight difference in girdle appearance, and how these
slight differences in painting or digging out create differ-
ences in face-up appearance, affecting the final GIA cut
grade accordingly.
For typical proportion combinations, observation testing
confirmed that diamonds with painting and/or digging out
beyond a certain degree were less preferred than
diamonds of similar proportions with standard
brillianteering. In agreement with these observations, the
GIA Cut Grading System will take into account various
extents and combinations of painting or digging out.
When a diamond is painted, face-up appearance is more
strongly affected through painting of the pavilion than the
crown. As pavilion painting increases, a diamond begins
to look like a single-cut diamond (a round diamond with
fewer facets) with strong wide areas of darkness in the
pattern. In combination with crown painting, the effect of
a dark and bright banded pattern is accentuated.
Face-up appearance is more sensitive to digging out.
Strong digging out on the crown causes upper half facets
to darken, blending with the bezel facets, which also
darken. Digging out on the pavilion can cause the entire
stone to have an interrupted pattern that takes on a strong
gray appearance, lacking in contrast. Digging out on both
the crown and pavilion causes the most extreme differ-
ences in appearance, darkening the center with unusual
bands of dark and light in the reflection pattern.
