The inextinguishable brilliance of diamonds has been revered by mankind over many
years. It has been a source of value and fascination throughout history. Known as
the symbol of eternity and love, each diamond is nature's work of art. Its beauty,
durability, value and rarity make it the most special gemstone.
Diamond Grading and 4C's
In the pursuit of absolute perfection, SRK manufactures diamonds with clarity and
flamboyant brilliance. We are constantly innovating and developing our manufacturing
technology to offer you brilliance you've never seen before.
Cuts are mainly arrangement of facets in the stone, affecting the cost and beauty
of a diamond. To what extend a diamond will reflect light from within, depends on
the skill and craft of the diamond cutter. When a diamond is cut with precision,
light gets reflected from one facet to another and results in a burst of brilliance.
An ideal cut diamond has maximum brilliance that is achieved through exact calculation
of the proportion and symmetry of the diamond. Brilliance reflecting out of the
table of the diamond makes it so alluring.
Brilliant cut diamonds have 58 facets, 33 on top and 24 at the bottom and the culet.
In this cut, all 58 facets appear to radiate from the center through the top of
the diamond. This is the most common diamond cut.
Step cut resembles stair steps due to the three concentric rows of facets arranged
around the table, culet and pavilion. Emerald cut is a good example of a step cut
Mixed cut diamonds combine the step cut and brilliant cut. For instance, the crown
of the diamond can be cut as a brilliant cut and the pavilion as the step cut.
Diamonds receive the FL (flawless) grade when there is no discernible inclusion
or blemish that causes interference with the passage of light through the stone.
At SRK, we offer diamonds that achieve a grade of VS2 and above. VVS and VS graded
diamond are highly expensive whereas SI1 and SI2 graded diamonds are more affordable.
A grading system has been established by the GIA for measuring the type and size
of these impurities:
FL , IF
Flawless and internally flawless
Very slight inclusion that is hard to view under 10x magnification
Slight inclusions that are visible under 10x magnification and may not be visible
to the naked eye
More light passes through diamonds that display little color, creating a prism-like
effect. If the stone is totally transparent, it becomes rarer; however, notable
exceptions are fancy colored diamonds such as yellow, green, blue and pink. Grades
are allocated to a diamond according to the level of color it possesses.
Based on the color scale established by the GIA (Gemological Institute of America),
a letter is assigned to the degree of colorlessness found in diamonds. Starting
from D and ending with Z, each descending letter denotes an increasing amount of
light (yellow, brown or grey) in the diamonds.
A gemologist can identify traces of colors found in the diamond even though the
stone looks colorless
These diamonds look almost colorless because untrained eye cannot notice the hint
of color present in the stone
These stones have faint traces of color
Color in the diamond is obvious even to the untrained eye
Carat determines the weight of a diamond with 1 carat being equivalent to 200 milligrams
or 0.2 grams. One carat is also divided into 100 points. These points are used for
describing increments of weight within a carat. A diamond's price per carat increases
in proportion with the size of the stone. Two diamonds of the same weight can have
different values based on their color, cut and clarity.
