Cut



Learning Diamond Cut

The cut determines the diamond’s light performance and its brilliance. The cut of a diamond will reflect light within, from one mirror-like facet to another, diffusing it consistently through the crown (top) of a diamond. If it has been cut too shallow and wide, the diamond will lose light through the bottom. If it has been cut too deep and narrow, the diamond will lose light through its sides.

Diamond Cut Chart Guide

4Cs of a Diamond

Colour – Diamonds are available in different colours – from transparent to “fancy” colours like pale yellow or brown, black to rare pinks, blues, greens and other colours known as "fancies". Choosing a diamond's colour is a matter of your personal preference.

Carat Weight – Diamond carat is the standard measure of its weight. The larger the diamond, the more rare it is. A carat (being an equivalent of 200 milligrams) is made up of 100 points. Thus, a diamond of 75 points weighs .75 carats.

Clarity – The clarity of a diamond depends on its cut and polish. Proportions and symmetry are of the highest value as these factors define its life, brilliance and dispersion.

Cut – The diamond cut refers to both the shape of a diamond and the aspects – their number, size and relative proportions – of a diamond's surface. It is the most important factor in enhancing a diamond’s light performance.

Cut Grades

This refers to the way a diamond is cut; its size, width, depth, roundness and the positioning of facets which determine the brilliance of the stone. Though colour and clarity are perfect, if a diamond is not cut to good proportions, it will be overcast and less impressive to the eye. At Empress Diamonds we stock only Good to Excellent cut diamonds

Excellent / Ideal cut –  The highest quality cut. This will reflect the maximum amount of light, having incomparable brilliance and fire - showing a superior level of craftsmanship, brilliance and light.

Very good cut – This has a very good light performance. It reflects almost all of the light that enters. Less expensive than an “Ideal” cut, but still offering brilliance and spark similar to the “Ideal” cut.

Good cut – It reflects most of the light that enters the diamond and is much less expensive than a very good cut.

Fair cut - Allows much of the light entering the diamond to escape through its sides or bottom, less fire and brilliance to be detected. Suitable for less than .75 carats where it differs in sparkle and is difficult to recognise.

Poor cut - They are usually deep and narrow, or wide and shallow, they lose most of the light through the sides and bottom. A poor cut diamond may be noticeably overcast and lifeless.
