Four different facets are taken into account while grading diamonds to ascertain their quality and value. These factors are cut, clarity, carat and colour. While using the grading system jewellers can compare different stones easily.

Colour:

The colour of the diamond is graded from D to Z, where D indicated a genuine white diamond - a colourless diamond - and Z indicates a diamond ring which includes yellow hues inside it. Because the grading progresses from D by way of Z these gemstones take on a yellowish tone. Diamonds which might be graded approximately H are categorized as white diamonds. People who are graded from I onwards begin to show a touch of yellow inside them. The colourless stones include the rarest of most making them probably the most valuable diamonds.



Clarity:

Diamonds are certainly not always perfect as a number of them have naturally occurring blemishes included. These blemishes may be because of fractures or minerals or inclusions as the diamond is made in the earth. These blemishes disrupt how a light flows in the diamond and based on the level and extent of blemishes in the diamond determines how it continues to be graded from Pure to Included (FL to I). Diamonds which are graded as pure/FL don't have any visible blemishes when seen under magnification whereas diamonds that are graded as included/I have blemishes which can be visible even with a human eye alone. The diamonds which might be without any blemishes are extremely valuable and rare. The grades starts from Flawless and Internally Flawless - Pure, VVS1 and VVS2 - Extra Small inclusions, VS1 and VS2 - Small Inclusions, SI1 and SI2 - Small Inclusions, I1, I2, and I3 - Included.

Cut:

Diamonds which might be perfectly located at the earth are cut to ensure that the stone has maximum sparkle and brilliance. Quality cut cause an engagement ring expensive and valuable which is the only ingredient that is affected by humans. In order to cut diamond jewelry perfectly, greater than 50% from the rough diamond will need to be cut away with the craftsmen. The grades to get a diamonds cut starts from Excellent - 1+ and 1, Good - 2 about three, Average - 4, Commercial - 5 and 6, and Irregular - 6 and 7.

A carat is really a unit which is used to measure the weight of gemstones which is one of many factors looked at while assessing the caliber of an engagement ring. Diamonds who have higher carat values have an overabundance of sparkle than diamonds with lesser carat value as light has to cross a more substantial distance.
