RRE Grading System

Diamonds do not show all of their beauty as rough stones; instead, they must be cut and polished to exhibit the characteristic fire and brilliance that diamond gemstones are known for. Diamonds are cut into a variety of shapes that are generally designed to accentuate these features.

Round

Cushion

Pear

Marquise

Heart

Oval

Emerald

Princess

Radiant

Asscher

Diamonds are graded for clarity on the basis of internal and external imperfections present. We grade the diamonds based on below parameter based on clarity.

The diamonds are also graded based on color. We are grading the diamonds in to parameter of White, LC (Light Color-Off White) and LB (Light Brown) based on color. The diamond which has red color shine can be graded as LB. LC grade includes yellow shade diamonds. As a rule, yellower the stone, lesser the value it has as compared to colorless diamonds.

Polish and symmetry are two other important aspects of the cut. Polish describes the smoothness of the diamond's facets (surface conditions), and symmetry refers to alignment of the facets (the exactness of shape and placement of the facets). Symmetry is an important element of diamond finish. Symmetry refers to the exactness of the shape and arrangement of facets. This includes naturals, misshapen and extra facets, off-center culets and tables, wavy and out-of-round girdles, misalignment of crown and pavilion facets. To the unaided eye, finish features usually have little effect on appearance; they are like pin point inclusions. The importance of symmetry is of lesser consequence in diamonds that have lower clarity grades whereas, it is more important in diamonds that have high clarity grades. Here also diamonds are graded as cut grade parameters like excellent, very good, good, fair and poor.
