4C's of Diamonds | Hari Krishna Exports Pvt. Ltd


Carat refers to the standard unit of weight for diamonds and other gemstones. Carat is measured by Hari Krishna Exports Pvt. Ltd. using a highly precise electronic scale. Two diamonds of same carat weight can vary in cost depending on factors such as color, clarity and cut of the diamond.

As the carat size of the diamond increases so does its cost because the larger the diamond, the rarer it is.


Color refers to a diamond's lack of color, grading the whiteness of a diamond. A color grade of D is the highest possible, while Z is the lowest. The less color a diamond has, the higher its color grade. After cut, color is generally considered the second most important characteristic when selecting a diamond. All diamonds are color graded in a lab. As a polished diamond concentrates its true color around the culet, colouring is viewed through the pavilion (ignoring girdle and crown) white table down in a white colouring card.


Clarity refers to internal features (inclusions) and surface characteristics (blemishes) within or on a diamond when viewed with 10x magnification under standard viewing condition. The Company clarity scale includes eleven clarity grades ranging from Flawless to I3 as per International standard. We also have parcel goods ranging from IF to I7.

FL/IF - Flawless, Internally Flawless: No internal or external imperfections. Internally Flawless: No internal imperfections. This is very rare.

VVS1/VVS2 - Very, Very Slightly Included: Very difficult to see imperfections under 10x magnification. This is considered to be an excellent quality diamond.

VS1/VS2 - Very Slightly Included: Imperfections are not typically visible to the unaided eye. It is less expensive than the VVS1 or VVS2 grades.

SI1/SI2 - Slightly Included: Imperfections are visible under 10x magnification, and may be visible with the unaided eye. It has a good diamond value.

I1-I3 - Included: This grade of diamonds will have minor inclusions that may be visible to the unaided eye. Inclusions are obvious under 10x magnification and may affect transparency and brilliance. I3 diamonds have large and extremely easy to see inclusions that typically impact the brilliance of the diamond, as well as having inclusions that are often likely to threaten the structure of the diamond.


Cut refers to a diamond's proportions, symmetry and polish. The beauty of a diamond depends on the cut as compared to any other factor. A diamond's cut is vital to the stone's beauty and value. And of all the diamond 4Cs, it is the most complex and technically difficult to analyse.

The cut scale contains 4 grades ranging from Excellent to Fair. Excellent, Very Good, Good and Fair.
