The Ideal Cut Diamond describes a round brilliant diamond that has been cut to exact mathematical proportions. The 58 perfectly polished facets create the ultimate in luster and brilliance. When a diamond is cut to the Ideal proportions, light entering from all directions is reflected through the top in a display of rainbow colors and sparkling flashes. When a diamond is cut too deep, the light leaks out of the bottom, brilliance is lost and the center of the diamond will appear dark. When a diamond is cut too shallow, light leaks out of the bottom.
Brilliance is lost and the diamond appears glassy, lifeless and dark.
As with all precious stones, the weight of a diamond is expressed in carats. Carat weight and cutting proportions give a diamond its size. The size, nature, quantity and location of inclusions determine a diamond's clarity grade and affect its rarity and value. A unique advantage of the polished perfect diamond is that its sparkle and fire enhance the life and brilliance of every diamond. Although most diamonds appear colorless, they do have slight shades of yellow or brown.
