Four different factors are taken into consideration while grading diamonds to discover their quality and worth. These factors are cut, clarity, carat and colour. While using the grading system jewellers compares different stones easily.

Colour:

The color of the diamond is graded from D to Z, where D indicated a true white diamond - a colourless diamond - and Z indicates an engagement ring which has yellow hues inside it. Because grading progresses from D right through to Z these precious stones take on a yellowish tone. Diamonds which are graded up to H are sorted as white diamonds. People who are graded from I onwards begin to show an indication of yellow included. The colourless stones include the rarest of most which makes them essentially the most valuable diamonds.



Clarity:

Diamonds are certainly not always perfect as many of them have naturally occurring blemishes inside them. These blemishes might be due to fractures or minerals or inclusions as the diamond is made on your lawn. These blemishes disrupt how the light flows inside the diamond and based on the level and extent of blemishes inside the diamond determines how it continues to be graded from Pure to Included (FL to I). Diamonds which might be graded as pure/FL have no visible blemishes when seen under magnification whereas diamonds which are graded as included/I have blemishes which might be visible despite a human eye alone. The diamonds which can be free of blemishes are extremely valuable and rare. The grades starts from Flawless and Internally Flawless - Pure, VVS1 and VVS2 - Super Small inclusions, VS1 and VS2 - Very small Inclusions, SI1 and SI2 - Small Inclusions, I1, I2, and I3 - Included.

Cut:

Diamonds which are located in the earth are cut to make sure that the stone has maximum sparkle and brilliance. Quality cut is what makes a diamond ring expensive and valuable and that is the only real ingredient that is influenced by humans. As a way to cut an engagement ring perfectly, more than 50% of the rough diamond will need to be cut away from the craftsmen. The grades to get a diamonds cut starts from Excellent - 1+ and 1, Good - 2 and three, Average - 4, Commercial - 5 and 6, and Irregular - 6 and seven.

Carat:

A carat is often a unit that is utilized to determine the weight of all gemstones which is one of the factors taken into account while assessing the grade of diamond jewelry. Diamonds who have higher carat values have more sparkle than diamonds with lesser carat value as light has got to cross a bigger distance.
