The 4 C's for Diamond Quality refer to the essential characteristics of diamonds: Carat, Color, Clarity, and Cut. Each of these factors plays a crucial role in determining a diamond's quality and value. The carat weight, color grade, clarity grade, and cut will determine diamond quality, but there’s no “right answer” to how a diamond should look. Many people in the market for an engagement ring will prioritize one factor in favor of another.
Carat Weight is the unit of measurement used to describe a diamond's weight.
Diamond color actually means thelack of color.
Diamond clarity is the absence of inclusions and blemishes.
Diamond cut is how well the diamonds facets interact with light.
