diamond is the largest purchase of their life. With that consideration,Carat Lane
recognizes the importance of understanding exactly what you are buying.This guide
simplifies the four Cs - cut, colour, clarity, and carat weight, as well as diamond
shapes and certifications. After reading this guide, you will be better prepared
to choose the diamond that is right for you.
- PRINCES
This is our most popular non-round Diamond. Its beautiful brilliance and unique
cut makes it a favorite for engagement rings. The princess has pointed corners and
is traditionally square in shape. When choosing a color grade, consider that while
the prince of a J-color non-round diamond is exceptionl,color may be slightly visible
in its corners. Also, princess-cut diamonds can vary greatly in how square or rectangular
they are. To find the dimention of princess you want, look for the length-to-width
ratio in our interactive diamond search and on each diamond’s detail page. This
will determine what the diamond will look like when viewing it from above. Here
are length-to-width ratios for princess-cut diamond shapes that are pleasing to
the eye.
- EMARALD
What makes this shape different is its pavilion, which is cut with rectangular facets
to create a unique optical appearance. Due to its larger,opentable,this shape highlights
the clarity of a diamond. If you choose an emerald-cut with a lower clarity grade,
such as DI, be sure to review the clarity plot on the diamond certificate. Also
,emerald-cut diamonds can vary greatly in how rectangular they are. If you’d prefer
an emerald cut want,look for the length to width radia in our interactive diamond
search and on each diamond’s detail page. The lenth to width ratio will determine
the diamond’s outline, or what it will look like when viewed from the top.
- MARQUSES
The shape of Marquise Diamond can maximize carat weight, giving you a munc larger-lloking
diamond. This brilliant –cut diamond looks beautiful set with tound or pear-shaped
side stones,and the length of the marquise makes fingers appear long and slender.
To find the dimension of marquise you want,look for the lengh to width radio in
our interactive diamond search and on each diamond’s detail page. The length to
width radio will determine the diamond’s outline, or what it will look like when
viewed from the top.
- OVAL
An oval Diamond has beautiful brilliance that’s similar to a round diamond. Oval
diamonds are also very popular as their length can accentuate long, slender fingers.
To find the dimension of oval you want, look for the length to width ratio in interactive
diamond search and on each diamond’s detail page. The length to width ratio will
determine the diamond’s outline, or what it will look like when viewed from the
top.
- RADIANT
Trimmed corner are the signature of this diamond, and they help make the radiant-cut
a popular and versatile choice for jewelry. A radiant-cut looks equally beautiful
set with either baguette or round side–diamonds. Radiant-cut diamonds can vary in
their degree of rectangularity. To find the dimension of radiant you want, look
for the length to width ratio in our interactive diamond search and on each diamond’s
detail page. The length to width ratio will determine the diamond’s outline, or
what it will look like when viewed from the top.
- PEAR
This Brilliant cut diamond is also called a teardrop for its single point and rouded
end. The unique look of the pear shape helps make it a popular choice for a variety
of diamond jewelry. If you choose an elongated pear shape, the length of the diamond
creates a subtle slimming effect on the fingers.
- HEART
The heart is the ultimate symbol of love. The unique look of the heart-shaped diamond
helps make it a distinctive choice for a variety of diamond jewelry. When choosing
a color grade, consider that while the price of a J-color heart shaped diamond is
exceptional, color may be slightly visible in its corners. To find the dimension
of heart-shape you want, look for the length to width ratio in our interactive diamond
search and on each diamond’s detail page. The length to width
- Cut:-
- The Cut determines
The diamond’s brilliance and beauty
The diamond’s ability to reflect light
The diamond’s proportion,symmetry and finish
A well-cut diamond appears brilliant and fiery, while a badly cut diamond looks
dull and lifeless, despite having a good colour and clarity grade.
The Cut is a set of measurements based on how light travels within the diamond and
exits from the top. The Cut is the only “man-made” C of the 4C’s
Gemmologists consider Cut the single most important factor that defines the brilliance
of a diamond.
Do not confuse Cut with Shape. Cut refers to how well the diamond has been designed
and proportioned by the cutter. Shape refers to the general silhouette or outline
of the diamond.
An ideally proportioned diamond is cut according to scientific formulae calculated
to maximise brilliance. In such diamonds, light that enters the stone from the top
will bounce about within the diamond to create multiple reflections, which exit
the stone from the top, causing the diamond’s glitter.
Diamonds that are cut too deep or too shallow lose or leak light through the side
or bottom. The result is less brilliance, and ultimately less value for the diamond.
- Pic of
cut
The most important proportion is the ratio between the depth and the diameter of
the diamond. The ideal ratio is 58.5%, but slight deviations are acceptable. The
ratio between the height of the crown and that of the pavilion is also important.
Please remember that this ideal ratio applies only to the Round Brilliant shaped
diamonds. Gemologists differ on the ideal depth percentages to be followed in the
other fancy shapes, and therefore, no ratios have been set as ideal for any of the
other shapes. Other factors that count are length of the, pavillon facets, size
and shape of the various crown facets, size of the table and the culet.
- Polish
and Symmetry
- Polish
Dramatically amplifies brilliance of a well-proportioned diamond Is crucial in diamonds
of very high clarity grades
- Symmetry
Gives the diamond its final appearance Is crucial to its brilliance Ensures smooth
passage of light through the diamond Diamonds with poor polish are less brillant
due to microscopic lines thet reduce the amount of light that enters and exits the
stone.
- Rating
of the cut
The Gemmological institute of America (GIA),the authority in diamond certification,
grades diamond cuts as Excellent, Very Good, Good, Fair, or Poor.
- The GIA
determines cut grades on the basis of:
Brightness, Fire, and Scintillation
Weight Ratio and Durability
Polish and Symmetry
- What is
the best cut grade
If you are looking for the most exceptional diamonds that can attain the highest
gemological standards. These diamonds are cut to the exact proportions to get the
maximum brilliance. They have the best polish and symmetry grades available for
round diamonds, and our signature fancy shapes have either ‘excellent’ or ‘very
good’ polish and symmetry grades.
If you are looking for a round brilliant diamond that gives the best value for your
money, choose a diamond with a cut grade of ‘good’ or ‘very good’, and polish and
symmetry grades of ‘very good’ or ‘good’.
If the diamond you have selected has an ideal- or very-good cut with very good or
good polish and symmetry, you can buy lower grades of color and clarity — look for
a diamond with G or H color and SI1 or SI2 clarity.

- Carat Weight:-
Carat is the unit of measurement used to weigh diamonds. One carat is the equivalent
of 200 milligrams, or 0.2 grams. The word carat is derived from carob seeds that
owing to their very slight weight-variance, were used to balance scales in ancient
times. Due to the processes involved in the formation of nature, large diamonds
are created less frequently then smaller sized diamonds. Due to the rarity of larger
sized diamonds they command substantially higher prices than smaller sized diamonds.
For instance, a one carat diamond will cost more than two half carat diamonds of
equal colour, clarity and cut. However the weight of a diamond is but one of the
factors used to value a diamond, and it should be understood that two diamonds of
equal weight may have very different values, depending on their cut, clarity and
colour. In fact, a smaller but perfectly cut diamond of whiter colour and flawless
or near- flawless clarity can be more valuable than a larger diamond with a weaker
shade of white and less clarity. What to consider when deciding on diamond size:
It can often be difficult to choose between the size and the other criteria of a
diamond but by considering the following factors your decision may be made. (By
definition, 1 carat is 200 milligrams. Since most diamonds sold in the market weigh
less than 1 carat, the carat is usually subdivided into "points." There are 100
points in 1 carat, so that a diamond weighing 3/4 carat would be a "75 point diamond."
So Don’t confuse carat with karat, as in ‘’18k gold,’’ which refers to gold purity.
1 carat = 200 milligrams = 100 points
Diamonds of 0.5 - 0.75 carat are very popular for their combination of size and
value.
Personal preference – do you or your loved one prefer to wear larger pieces of jewellery?
Finger size – slender finger can make diamonds appear larger then thir actual size,
Physical activity – a person who is very physically active mare likely knock or
bump their ring,
Setting style – will the selected setting be aesthetically suitable to the diamond?
- Colors
While diamonds can be found in almost every colour of the rainbow, colourless diamonds
remain the most popular. When describing the colour of a diamond reference is being
made to the degree of colour found in that diamond. The less colour displayed in
a diamond the better the colour grade. The notable exception to this would be in
the case of fancy coloured diamonds, such as pink, yellow, green and blue. In fancy
coloured diamonds a strong presence of colour would improve the diamond’s colour
grading. Diamonds displaying little colour will allow more light to pass though,
creating a prism effect, with its spectrum of colours and flash, known as fire.
Diamonds are allocated a grade according to the level of colour they possess. This
grading is alphabetical, starting with a D grade given to colourless diamonds and
further movement down the alphabet for diamonds with progressively larger amounts
of colour, ending in a Z+ grade. The colour grades can be described as follows:
The ideal diamond is completely colourless, and the most expensive. However, most
diamonds which appear colourless actually have slight tones of yellow or brown.
The Gemmological Institute of America (GIA), the authority in diamond certification,
grades colour alphabetically from D (totally colourless) to Z (heavily tinted).
- D -Absolutely
colouriess.
The ideal diamond is completely colourless, and the most expensive. However, most
diamonds which appear colourless actually have slight tones of yellow or brown.
The highest colour grade, which is extremely rare.
- E-Colorless.
Only minute traces of colour can be detected by an expert gemologist. A rare diamond.
- F - Colorless.
Slight colour detected by an expert gemologist, but still considered a colorless
grade. A high-quality diamond.
- G - H Near-Colorless.
Colour noticeable when compared to diamonds of better grades, but these grades offer
excellent value.
- I - J, K Near-colorless.
Colour slightly detectable. An excellent value.
- L - M Noticeable
colour.

- N -Z Noticeable

Yellow shades, found in I - M graded diamonds, may draw out the latent character
of a jewellery piece, depending on the piece selected.
- Clarity
As a product of nature diamonds may bear traces of the pressure and processes involved
in their formation. These traces may appear on the diamond either externally, or
internally and are referred to as ", inclusions",Where appearing internally
on the diamond these inclusions may include air bubbles, cracks and non-diamond
mineral deposits. Inclusions appearing externally may include scratches, pits and
chips. Not all diamonds have inclusions, and those without, are rare and often the
most expensive. Diamonds with inclusions are graded according to the amount of inclusions
detected. Diamonds are graded for clarity under 10x magnification. Grading is allocated
to a range of diamonds from "Flawless" to "Included-3" according
to the following the following grades:
FL: Completely flawless
IF (Internally Flawless) or LC (Loupe Clean):
VVS1-VVS2 (Very Very Slightly Included): These inclusions are detectable under 10x
magnification, and are also visible to the human eye.
VS1-VS2 (Very Slightly Included): Tiny inclusions which are difficult to detect
under 10x magnification;
SI1-SI2 (Slightly Included): Tiny inclusions which are detectable under 10x magnification;
I1-I3 (Included): These inclusions are detectable under 10x magnification, and are
also visible to the human eye.
- Certification
Certificates are proof of a diamond's identity, authenticity and value. A certificate
will indicate a diamond's exact measurements, weight, cut and overall quality. A
certificate will precisely point out a diamond's individual characteristics as well
as be a useful tool while identifying a stone.
