Before you start shopping, you need to have a prior understanding of what you're buying. It's quite common to confuse a diamond's cut with its existing shape. The cut actually describes a diamond's light performance, dimensions and finish. With the below given information you can understand the process of cutting a and choosing them with light performance.

Cutting Process

The process of cutting or shaping a rough into a polished gemstone is a task of both an art and a science. The choice of cutting a is often decided by the original shape of the rough stone, location of the inclusions and errors to be eliminated, and preservation of the weight, some popularity of shapes amongst consumers and with many other considerations. The round brilliant cut is normally preferred when the crystal is an octahedron, as often two stones might be cut from one of such crystal. Oddly shaped crystals such as macles are preferred to be cut in a fancy way that is a cut other than the round radiant.

With the modern techniques, the cutting and polishing of a crystal mostly results in a dramatic weight loss in diamond; rarely is it less than 50%. Sometimes it is possible that the cutters compromise and accept lesser proportions and symmetry in order to avoid inclusions or may be to preserve the carat rating. Since per carat price of shifts around key milestones (such as 1.00 carat), numerous one-carat diamonds are the result of negotiation "Cut" for "Carat." Some jewelry experts do advise consumers to buy a 0.99 carat for its better price or to buy a 1.10 carat for its fine cut.

Light Performance

Diamond’s beauty is recognized by the way it shines, sparkles, and the light it produces. Logically having accurate quantitative and qualitative analysis of the light being returned by a could certainly be very helpful in determining its beauty and evaluating its cut quality.

The light performance concept was initially introduced by GemEx in 1998, and then AGS introduced their version in 2005 and GIA introduced their version this 2006. Light performance deals with the amount of light produced what kind of light and the origin of light emitted or reflected by a source.

To understand and measure the light dynamics performance and behavior of a is certainly a historic and

probably the most significant event in modern history, which would affect how a should be cut to maximize beauty. Prior to this time there was actually no technologies or protocol, which might relate a diamond’s actual light performance with the proportions and angles it was cut. Much of the idea on how much brilliance a round can be produced was based on theory not by measurement.

As we know cut describes a diamond's light performance, dimensions and finish. Shape refers to the overall and real outline of the when viewed from the top. Since all shapes are very different, unique characteristics determine excellence for each shape be careful while choosing the most beautiful for you.
