Diamond Cut

Diamond Cut

A cut in a diamond is not only about its shape but how the light passes though it and sparkles from the surface. An ideal cut in a diamond is a perfect combination of three essential features which is brilliance, fire and scintillation achieved by the diamond cutter. To determine the overall beauty of a well cut diamond it is important to achieve ideal proportions and angles to refract light through the table & crown of the diamond with fine polish and symmetry grading. A poorly cut diamond on the other hand will appear lifeless and dark, regardless of its deeply significant clarity or color.

Diamond Proportion refers to a relationship between shape, size and angle of each facet of a diamond. For a diamond to show its maximum light it needs to be exhibiting three primary factors: brilliance, dispersion and scintillation. When the light hits the diamond surface and reflects back to the eye of the observer, is known as brilliance or brightness. It bounces off the mirror like facets reflecting white light from the table of polished diamond. When the light enters through the gem, some light is broken down to rainbow of spectral colors and is reflected back to eye of the observer, is known as dispersion or Fire. The separation of light into flashes of color refers to Fire. Further scintillation is ability of the light to reflect or refract with the movement of a diamond, shown by sparkling effect on diamonds surface.

At DIAMERA, we aim to offer only GIA graded diamonds with finest cut and magnificent polish which is affordable to buy. Furthermore all our listed diamonds are always shown with GIA cut grade.

The effect of light from the table to the culet of a diamond, DIAMERA provides a guide to understand characteristics of sparkling diamond. Below we have used an illustrative diagram of a round cut diamond as most other diamond shapes such ‘Fancy cut’ has a more complex cut grading as per GIA.
