These four qualities of a diamond are the key components that impact its beauty and structure.
The 4C’s interact within a diamond. They dictate how the diamond appears and it’s quality.
For example, the diamond’s ability to reflect light back to your eyes depends primarily on
cut quality, color, and clarity.
Good proportions, symmetry, and polish affect diamond beauty more than perfect color or
clarity. The cutting grade is determined by the diamond cutter’s effort to maximize light
refraction at every stage of the manufacturing process. Most brilliant-cut or fancy-shaped
diamonds possess fifty-eight carefully angled flat surfaces, called facets, whose placement
will affect the fire, brilliance, and ultimate beauty of your diamond. Proportion is the single
most important factor because it determines light flow more than any other quality factor.
Royal Diam has developed several grading methods to help consumers determine the cut of
a particular diamond. In general, these grades are Ideal, Very Good, Good, Fair & Poor.
The Royal Diam Grading System RGS uses a combination of factors such as symmetry,
proportion, and polish to evaluate the cut of a diamond. This helps consumers assess the
quality of the diamond and decide which is best for their needs.
