A Diamond's Cut

Of the 4 C's, the diamond's cut is the most important factor in determining its brilliance and beauty of a diamond. There are many shapes that diamonds are cut to but a diamonds cut refers to how well proportioned the diamond has been transformed into its shape. The shape of a diamond can be round, oval, pear, heart, marquise, emerald or princess. When speaking of a diamonds 'cut grade', we are referring to its proportions, symmetry and polish. Novori will not sell diamonds with a cut grade considered less than very good. Ideally, the cut of the diamond is done in a way to best reflect the light that shines into it. This is what produces the sparkle and fire we see in a beautifully cut diamond. GIA grading reports show depth % and table % ratios as compared to the width of the diamond. A good table cut should be 53-64% and a good depth cut is 58-64%. If the cut is outside of this range the diamond is considered to be cut too deep or too shallow. If the diamond is cut too heavy, or too shallow, most of the light entering into the crown is released through the bottom of the pavilion resulting in an overall dull appearance. An ideal cut diamond on the other hand, returns most of the light that enters it back through the crown giving it a very satisfying sparkle effect.

Red Diamond For Sale

The Argyle Diamond Mine in Australia is famous for being the world’s premier source of pink colored diamonds but it is also the premier source of the few red colored diamonds known to exist. To say that there is only a small number of true natural red colored diamonds is no exaggeration.

Quality of a Diamond

The quality of a diamond's cut is widely considered the most important of the four Cs in determining the beauty of a diamond; indeed, it is commonly acknowledged that a well-cut diamond can appear to be of greater carat weight, and have clarity and colour appear to be of better grade than they actually are. The skill with which a diamond is cut determines its ability to reflect and refract light. In addition to carrying the most importance to a diamond's quality as a gemstone, the cut is also the most difficult to quantitatively judge. A number of factors, including proportion, symmetry , and the relative angles of various facets, are determined by the quality of the cut and can affect the performance of a diamond. A poorly cut diamond with facets cut only a few degrees out of alignment can result in a poorly performing stone. For a round brilliant cut, there is a balance between "brilliance" and "fire."
