    Four various factors are considered while grading diamonds to ascertain their quality and value. These factors are cut, clarity, carat and colour. With all the grading system jewellers can compare different stones easily.


    The colour of a diamond is graded from D to Z, where D indicated a true white diamond – a colourless diamond – and Z indicates a diamond that has yellow hues in it. Because the grading progresses from D by way of Z these do undertake a yellowish tone. Diamonds which can be graded up to H are classified as white diamonds. People who are graded from I onwards begin to show a touch of yellow within them. The colourless stones include the rarest coming from all which makes them the most valuable diamonds.


    Diamonds usually are not always perfect as some of them have naturally sourced blemishes included. These blemishes could be as a result of fractures or minerals or inclusions whilst the diamond is actually created in the earth. These blemishes disrupt the way the light flows within the diamond and based on the level and extent of blemishes within the diamond determines the way may be graded from Pure to Included (FL to I). Diamonds which might be graded as pure/FL haven’t any visible blemishes when seen under magnification whereas diamonds that are graded as included/I have blemishes that are visible despite having a human eye alone. The diamonds which are without any blemishes have become valuable and rare. The grades starts from Flawless and Internally Flawless – Pure, VVS1 and VVS2 – Super Small inclusions, VS1 and VS2 – Really small Inclusions, SI1 and SI2 – Small Inclusions, I1, I2, and I3 – Included.


    Diamonds which might be located in 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 sole ingredient that is influenced by humans. As a way to cut a diamond ring perfectly, greater than 50% in the rough diamond will need to be cut away by the craftsmen. The grades for the diamonds cut starts from Excellent – 1+ and 1, Good – 2 and 3, Average – 4, Commercial – 5 and 6, and Irregular – 6 and 7.


    A carat is often a unit that is utilized to measure the load of gemstones which is one of many factors taken into account while assessing the grade of a diamond. Diamonds that have higher carat values have an overabundance of sparkle than diamonds with lesser carat value as light has got to travel through a larger distance.
