Diamond Cuts

When the diamond is mined originally, it is extremely rough and does not look half as shiny and sparkling as you see it in retail stores. Besides, it doesn’t even have the beautiful round or square shape that is seen embedded in jewelry pieces. To achieve the look that would attract buyers in droves, diamond needs to be cut, smoothed and polished to perfection.

Diamond cutting is essentially a process that transforms the raw form of diamonds into a polished diamond. Diamond cutters use a slew of specialized techniques to make the rough crystal into tiny and glittering diamonds.

A diamond cut is a style or design guide used when shaping a diamond for polishing such as the brilliant cut. Cut does not refer to shape (pear, oval), but the symmetry, proportioning and polish of a diamond.

The size of a diamond may also be a factor. Very small (< 0.02 carats [4 mg]) diamonds—known as melée—are usually given simplified cuts (i.e., with fewer facets). This is because a full-cut brilliant of such small size would appear milky to the human eye, owing to its inability to resolve the stone's dispersive fire. Conversely, very large diamonds are usually given fancy cuts with many extra facets.

Ideal Cut: - Ideal cut diamonds maximize the brilliance that is reflected out of the table of a diamond. This maximum brilliance is achieved through the exact calculation of the diamonds symmetry and proportions. When finished with the highest standards in polishing of the surface of the stone, these diamonds become the best available.

Excellent Cut: - While generally also displaying maximum brilliance, excellent cut diamonds are not as exacting in terms of their symmetry and proportions.

Very Good Cut: - In a very good cut most of the light that enters the diamond will be reflected back though the table, creating a high amount of brilliance. Craftsmen working on these diamonds would have made the decision to stray slightly from the proportions and symmetry of ideal cut and excellent cut diamonds, to create a larger diamond.
For example a very good cut diamond may have a table size or girdle width that does not comply with ideal cut or excellent cut diamonds. However, in many instances, very good cut diamonds will possess symmetry and proportion characteristics that overlap with those of ideal cut and excellent cut diamonds. These diamonds provide a very good value purchase for buyers seeking a slightly larger diamond for the same price as ideal cut and excellent cut diamonds.

Good Cut: - These diamonds will reflect much of the light that enters them back through the table. In such diamonds the craftsmen have significantly deviated from the proportions of ideal cut and excellent cut diamonds to create the largest possible diamond from the original rough crystal diamond. By way of an example these diamonds may have a crown angle or depth that is further deviated from the proportions acceptable in a very good cut. These diamonds may provide the option of a larger diamond then a very good cut diamond for the same price.

Fair and Poor cut: - A fair or poor cut diamond will only reflect a small amount of the light that enters, back though the table. Most usually these diamonds have been cut where maximum carat weight was the most important criteria.
