Naturally, diamonds are crystals of different sizes and shapes
that formed in the Earth, millions of years ago. The diamond
cutter’s art is what transforms these crystals into the beautiful
and dazzling precious stones named diamonds. Diamond cutters are
the artisans whose skills allow them to reveal the potential of
the raw crystals transforming them in sparkling gems of enchanting
beauty and brilliance.

Diamond shapes are punctiliously
and mathematically cut to enhance each stone’s features, and they
range from the classic round brilliant, which is the most popular
diamond shape, to the sophisticated Marquise cut.

Round Brilliant Cut. This is the most popular diamond shape,
being over 50% of the diamonds available of this shape.
This cut results in the most brilliant diamond shape
possible; for this reason, round brilliant cut diamonds
are frequently chosen for solitaire rings, displaying and
enhancing their unique brilliance. A round cut diamond
has 58 facets, 33 of them on the crown or top and 25 on
the pavilion or bottom.

Princess . After the round brilliant, princess cut diamonds are
the secondly most demanded, even though this shape does not
permit maximum brilliance due to its four corners which leak
out light. It is preferred because it is an undeniably elegant
cut, that though classic has a touch of modernity with its
acute corners.

Oval. The oval cut results in an elongated classical and stylish
diamond that produces a strong visual impact. It is common to find
this shape in three-stone rings, being the oval the central piece.
It has 58 facets that maximizes carat weight, since its shape makes
it look larger than round cut diamonds of same weight.

Emerald. The emerald cut diamond has only 25 facets, therefore it
has fewer surfaces to reflect light off and makes inclusions
easily detectable by the eye. It is mandatory to choose a better
clarity and higher color grade when buying an emerald cut diamond.
This shape was one of the first cuts used in jewelry, and it is
one of the most glamorous and charming shapes.

Asscher. This diamond cut is also a rectangular shape,
somehow similar to the emerald cut. It is also known as
Hall of Mirrors due to the astonishing optical illusion
and brilliance. This is the cut of the largest known diamond,
the Cullinan Diamond, an unrivaled 3,205 carat diamond that
belonged to British King Edward VII.

What makes the Asscher diamond shape unique is that there are not set
numbers or strict guides to follow when cutting the stone.
It depends on the cutter’s art to maximize the beauty and
light performance of this squared diamond shape of 50 or 58

Radiant. The radiant shape refers to a square or rectangular diamond
shape that blends the brilliance of the round cut with the style and
distinction of the emerald and princess cuts. It consists of 70
facets smartly cut in order to enhance the magnificence and
light performance of the precious stone.

Pear. Pear shaped diamonds are hybrids that combine the best properties
of the marquise and oval shapes. Its teardrop sparkling shape makes the
pear shape optimal for the design of sumptuous and elegant pendants.

Cushion. Cushion cut refers to a particular square or rectangular shape
with rounded corners. Its shape resembles precisely the shape of a
pillow or cushion. This shape counts with large facets, that permit
enhanced light dispersion and results in an enchanting scintillating stone.

Heart. The heart shape is one of the most delicate diamond’s shape and definitely
the most romantic choice. It is usually made of 56 or 58 facets, and the number
of the pavilion facets can vary. Precise symmetry is essential for the beauty
and gorgeousness of the resulting diamond.

Marquise. The marquise diamond shape, also known as navette shape is the
fanciest diamond shape and the choice of the royalty. It is an elongated
shape that when properly cut will result in a diamond of utmost style and
brilliance. Typically, it is comprised of 58 facets, 33 of them on the
crown and 25 on the pavilion. The marquise shape is a great choice to
maximize the carat weight of the stone, since it makes diamonds look
larger than others of similar size and weight.


There are several factors that influence the beauty and price of a diamond.
One of the most relevant features to consider is the cut.

The cut implies the proportions and angles that are created when the
professional cutter takes the rough stone and transforms it into the
polished sparkling final diamond. It is precisely the cut what will
determine the brilliance of your diamond; it is what will allow the
light to reflect from one facet to the other, and on the top of it.

Dedicated workmanship and art are crucial to come up with a diamond of
the right proportions, symmetry and polish so that it can deliver
the most possible light.

Commonly, people assume that cut
and shape have the same meaning. However, this is not correct. The diamond
cut involves the shape and number of facets, as well as the quality of the
cut itself, which requires proportionality and finishing.

For example, the most common diamond shape is the round brilliant.
To evaluate the cut grade of it, the GIA scale considers the proportions
of it’s facets to determine how they interact with the light
and which final visual effects they produce. These effects include:

Brightness- How external and internal white light reflect from the stone
Fire- The white light scatters into all colors
Scintillation- The sparkling of the diamond and the light and dark zones within the stone.

Given all these considerations, there is a GIA Diamond Cut Scale, which is applied to standard round brilliant diamonds within the D to Z color range.
This Diamond Cut Scale classifies the cut as:

Excellent. Practically all light that enters the diamond ends up reflected
through the top. Produces an exceptional brilliance.

Very Good. Most of the entering light is reflected through the top of the diamond
and produces a high brilliance.

Good. These diamonds do not produce the
brilliance of those within first ranges. However, they are very bright.

Fair. Imperfections of the cut make these diamonds lose some light; therefore,
they are perceptibly duller.

Poor. Too shallow or too deep cuts make these diamonds lose a
lot of the light they can reflect, and their brilliance is noticeably poor.

The color of a diamond measures its level of transparency and influences in
its beauty and price.

The whiter a diamond is, the more amount of
light it can receive. The light that enters through the diamond, when reflected on
its facets go back out in the form of brightness and reflections. An uncolored
diamond receives more light, it looks more vivid than others with higher color
intensity. Uncolored diamonds are harder to find, which increases their price
and makes them more attractive.

Transparent and colorless diamonds are
considered the purest ones.

Most diamonds exhibit a light yellow to a
light brown color, which is within the normal color range. Yellow diamonds or
intense brown diamonds are known as “fancy color” diamonds.

The GIA developed a scale to measure the diamonds within the normal color
range. This scale goes from D (absolutely uncolored) to Z (yellow or light brown)
. Diamonds beyond Z fall in the “fancy” category.

From D to F on the GIA (Gemological Institute of America) diamonds are
classified as “colorless”. G to J comprises the “near colorless” diamonds,
K to M refer to “faint” category, N to R include the “very light”
colored diamonds, and S to Z includes the “light” colored diamonds.

Fancy diamonds beyond Z, can also be divided into fancy light, fancy,

fancy intense and fancy vivid.

The GIA also published the
Colored Diamond Grading Report, which describes the diamonds
that are not included on the normal color scale. They use a
list of 27 sub-gradings that cover the full spectrum. The
tone and saturation is described using 9 descriptive terms:
faint,very light, light, fancy light, fancy, fancy intense,
fancy dark, fancy deep, and fancy vivid

The diamonds that fall into the GIA scale are graded according to their transparency,
being the ones on the most uncolored range of such scale the most valuable ones.

However, fancy colored diamonds, are valued in a
different manner. The criteria to apply is the rarity of the
color and its intensity or color saturation. Diamonds with
an unusual intense color are the most expensive ones.

Diamonds are formed in the deep soil. The extreme heat
and huge pressure that help to form them, can also create certain imperfections.
These imperfections can be both internal (named inclusions) or external and are
considered the birth marks of each diamond. In most cases, these can only be
noticed under a potent microscope and do not affect the appearance or beauty
of the precious stone.

When a professional gemologist evaluates or
classifies the clarity of a diamond, represents these “inclusions” or
“external blemishes” in a graphic way, so as to create the diamond’s
unique “finger print”. Plotting the imperfections is what justifies
the clarity grade of the stone and what allows identifying it at
any future moment. The expert determines the number, type and position of
these unique features and how it affects the overall appearance of the diamond.

There is no perfect diamond, but when a diamond has minimal and tough to detect
imperfections, its clarity and value will be higher.

The Diamond Clarity Scale of the GIA classifies diamonds in 11 grades which

1. Flawless. No inclusions or blemishes seen under a 10x magnification

2. Internally Flawless. No inclusions can be seen under 10x magnification

3. Very Very Slightly Included (VVS 1 and 2). Inclusions very hard to detect under
10x magnification

4. Very Slightly Included.(VS1 and 2) Minor inclusions which are hard to observe
under 10x magnification.

5. Slightly Included.(SI 1 and 2) Inclusions
are visible under 10x augmentation.

6. Included.(I1, 2 and 3) Evident
inclusions under 10x amplification, that may impact on the clarity and brilliance
of the stone.

The five factors that determine how inclusions are considered
and are used to grade its clarity are: nature, size, location, number and relief.

The human eye can not differentiate a VS1 from an SI 2 diamond, but this
difference affects the total quality and price of the diamond, therefore,
a professional should determine the clarity level of the diamonds.

Carat Weight

Diamond’s carat is a weight unit, frequently confused with size. Originally,
diamond traders used the carob seed to measure the diamonds, and that is
the origin of the term carat, and of the erroneous popular idea that carat
refers to size. Another common mistake is confusing diamond’s carat weight

with the karat’s gold purity measure. A carat equals to 0.2 grams.

Diamonds are sold by carats. However, two diamonds with the same carat
weight can have totally dissimilar prices depending on the other value
determinant factors: clarity, cut and color.

Carats are divided
into 100. Each fraction is called point, which means that, for instance,
a 40 point stone weights 0.40 carats. A single point or carat fraction
can have a noticeable difference in the value of the diamond, and diamonds
heavier than one carat are uttered in carats and decimals.

The importance of the carat of a diamond is fundamental to know its
value, and the larger the weight of the diamond, the noticeably huger
the price. This value variation increases at exponential rates since
larger diamonds are much rarely found. Therefore, a 3 Ct diamond does
not triplicate the price of a 1Ct diamond; the difference is much higher.
So, for example, if you own a ring with various small diamonds that
together total one carat weight (TW)and you also have a solitaire
ring with a single one carat diamond, the second one is definitely
the more expensive of them.
