While considering the cut of a diamond is the most important factor for its beauty, the cut determines the brilliance of the diamonds. This is based on reflection, dispersion, and scintillation of the light. Unlike color and clarity, there is not a single grade that defines it.
The cut is the most complicated of the 4Cs. Carat weight, color, and clarity, with their value and rarity, resulting in a diamond’s formation. Cut precision is the result of human decision and diamond cutting skills. Nowadays, it’s possible to have a better cut with the use of high technology in the diamond industry.
FACTORS FOR DETERMINING DIAMOND CUT QUALITY:
Proportions: the relative sizes and angles of the diamond’s parts and facets
Symmetry: the precision of the cut design, especially the facets
Polish: the smoothness and luster of the diamond’s surface
Raw diamonds need to be cut and polished into a polished diamonds in order to be ready for sale.
The quality of a diamond’s cut is determined by various proportions. Major is How its been Faceted with reference to different proportion that Reflect best light and evenness. According to the grading scale, the cut can be poor, fair, good, very good, and excellent.
Diamond cutters are aware how certain proportion combinations enable the diamond to capture light as well as possible, and also maximize its brilliance and sparkle.
However, when faceting the rough diamond, the proportions are not the only thing that should be taken care of, as the cut influences the other features of a diamond.
Many times it is impossible to cut a diamond that are quite big and clear to exacet excellent proportions. Because faceting them in exact manner might loose much weight and we loose the even size parameters. This will not only reduce the size but subsequently also reduce its overall value. So many times in order to achieve higher Yield out of rough the optimal and most desired result
Although these are the crucial or basic factors that determine the value and price of a diamond, there many different factors too that determines Basic quality and value of a polished diamond.
Henceforth, you can see the reference of cut grades on a diamond’s certificate. Often using the GIA standards of Excellent, Very Good, Good, Fair, and Poor. For the most part, the actual measurements are found on the laboratory reports.
