Clarity
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 BLACK DIAMOND, we offer diamonds that achieve a grade of VS2 and
above. VVS and VS graded diamonds are expensive whereas SI1 and SI2 graded diamonds are more affordable.
A grading system has been established by the IGI(International Gemological Institute) for measuring the type and size of these impurities:
FL , IF
Flawless and internally flawless
VVS1, VVS2
Very minute inclusions that are hard to view under 10x magnification.
VS1, VS2
Slight inclusions that are visible under 10x magnification and may not be visible to the naked eye.
SI1, SI2
Slightly more prominent inclusions that are visible under 10x magnification and may not be visible to the naked eye.
FL , IF
Flawless and internally flawless
VVS1, VVS2
Very minute inclusions that are hard to view under 10x magnification.
VS1, VS2
Slight inclusions that are visible under 10x magnification and may not be visible to the naked eye.
SI1, SI2
Slightly more prominent inclusions that are visible under 10x magnification and may not be visible to the naked eye.

SI1, SI2
Slightly more prominent inclusions that are visible under 10x magnification and may not be visible to the naked eye.
Color
More light passes through diamonds that display little color, creating a prism-like effect. If a stone is totally
transparent, it is considered rare; 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 IGI(International Gemological Institute), a letter is assigned to the degree of
colorlessness found in diamonds. Starting from D and ending with Z, each letter in descending order denotes an increasing
amount of light (yellow, brown or grey) in the diamond. for measuring the type and size of these impurities:
D
D is the highest color grade attributed to a diamond, denoting that the stone is completely colorless (white).
E, F
A gemologist can identify traces of colors found in the diamond even though the stone looks colorless.
G, H, I
These diamonds look almost colorless because the untrained eye cannot notice the hint of color present in the stone.
J,K,L
These stones have faint traces of color.
D
D is the highest color grade attributed to a diamond, denoting that the stone is completely colorless (white).
E, F
A gemologist can identify traces of colors found in the diamond even though the stone looks colorless.
G, H, I
These diamonds look almost colorless because the untrained eye cannot notice the hint of color present in the stone.
J,K,L
These stones have faint traces of color.
D
D is the highest color grade attributed to a diamond, denoting that the stone is completely colorless (white).

These diamonds look almost colorless because the untrained eye cannot notice the hint of color present in the stone.
J,K,L
These stones have faint traces of color.
Carat Weight
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.
