For fancies, the smallest diameter (width as opposed to length) is used. For example, if the table measures 5.7 mm, and the total diameter of the diamond measures 10.0 mm, then the table percentage is 57%.FinishThe finish of a diamond includes two separate factors: the polish and symmetry. The finish is a very good indicator of the care taken by the craftsman to make the diamond as beautiful as possible. This is one of the most contributing factors to the cut grade and cut quality of a diamond. We do not recommend engagement solitaire diamond rings with Poor or Fair grading for polish or finish.Most people just write or say it as a 1.6 ratio.Depth PercentageDepth percentage refers to the ratio of the average depth of the diamond (from table to culet) as compared with the average diameter (which is used as the 100% figure for all diamond dimensions). The ranges that are commonly considered best for each shape vary slightly, but we will just give the basic dimensions for rounds here: Ideal = 58 – 60%Excellent = 60.1 – 62%Good = 62 – 64%Fair = 64 – 66%Poor = over 66% or under 57%Table PercentageTable percentage is the ratio of the table width as compared to the total width of the diamond. For rounds, the largest diameter is used.
GIA established the standards and methods for a diamond evaluation, which all labs now follow. If you find the solitaire diamond rings are diamond that isn’t accompanied by a grading report, ask your seller to send it to a reputable lab to have it evaluated. Some points to bear in mind while buying your favorite diamond ring are discussed below:MeasurementsThe measurements of a diamond are primarily used for identification purposes, since no two diamonds are exactly alike in weight, quality and measurements together. For fancy shape solitaire diamond rings like the princess, marquise or pear shapes, the overall length-to-width ratio is important because certain proportions are more appealing to the eye. To compute the length-to-width ratio of a fancy-shaped diamond (;fancy shape; means anything other than round brilliant), take the length of the diamond and divide by the width. Example: A marquise that measures 8 mm x 5 mm has a 1.6:1 ratio.A Diamond Grading Report is a report or certificate issued by an independent Gemological Laboratory, which states that a diamond (usually over 1 carat) has been examined using various gemological instruments, compared to similar master diamonds, and has been found to contain the characteristics listed in the grading report. The Gemological Institute of America, GIA, is the largest and most well known laboratory in the world and as such, a diamond accompanied by a GIA report will cost more, although the diamond may not be worth more.
