Cut is arguably the most crucial of the 4C’s. It refers to how well a diamond’s facets interact with light. A well-cut diamond will exhibit brilliance, fire, and scintillation, making it sparkle and catch the eye
Color in diamonds refers to the absence of color. The Gemological Institute of America (GIA) grades diamonds on a color scale from D (colorless) to Z (light yellow or brown). The less color a diamond has, the higher its value.
CClarity measures the presence of internal inclusions and external blemishes. The fewer imperfections a diamond has, the higher its clarity grade..
Carat Weight refers to the size of the diamond. One carat is equivalent to 200 milligrams. Diamonds are often weighed to the hundredth decimal place, and every fraction of a carat can influence the price of the diamond. Larger diamonds are rarer and thus more valuable.
