The color of the diamond is graded from D to Z, where D indicated a real white diamond - a colourless diamond - and Z indicates a diamond which has yellow hues inside. Since the grading progresses from D to Z these do handle a yellowish tone. Diamonds which might be graded as much as H are categorized as white diamonds. People who are graded from I onwards begin to show a hint of yellow inside them. The colourless stones will be the rarest of which makes them probably the most valuable diamonds.
Diamonds are certainly not always perfect as some of them have naturally sourced blemishes in them. These blemishes could be because of fractures or minerals or inclusions as the diamond is made in your yard. These blemishes disrupt how a light flows inside the diamond and with regards to the level and extent of blemishes within the diamond determines the way has become graded from Pure to Included (FL to I). Diamonds that are graded as pure/FL have no visible blemishes when seen under magnification whereas diamonds which are graded as included/I have blemishes which are visible despite a naked eye. The diamonds which can be free of blemishes are incredibly valuable and rare. The grades starts from Flawless and Internally Flawless - Pure, VVS1 and VVS2 - Super Small inclusions, VS1 and VS2 - Tiny Inclusions, SI1 and SI2 - Small Inclusions, I1, I2, and I3 - Included.
Diamonds which can be found in the earth are cut to ensure that the stone has maximum sparkle and brilliance. Quality cut is why diamond jewelry expensive and valuable and this is the sole ingredient that is influenced by humans. In order to cut an engagement ring perfectly, over 50% from the rough diamond must be cut away through 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.
