Carat: Worth its Weight

Harry Winston diamonds are world-renowned for their outstanding quality. The size of such a diamond is an expression of its rarity: larger stones are generally more valuable because they are harder to find in nature. A diamond’s size is measured in carat weight: one carat equals 100 points, or one-fifth of a gram. But it is important to remember that diamonds of equal carat weight can vary greatly in value because they differ in the quality of their cut, color, and clarity—all of which also contribute to the beauty and prestige of a Harry Winston diamond. A diamond’s weight or size is the most obvious feature of a stone, but it is just one of many defining characteristics. Each Harry Winston diamond is a culmination of expertly selected criteria.

Beyond the 4Cs is the soul or character of the stone. Inspired by Mr. Winston’s passion and uncompromising search for the most exceptional diamonds, Harry Winston’s gemologists select only the finest diamonds in the world. Stones with similar attributes can vary greatly in beauty and character, and that is why Winston’s seasoned experts look beyond the grading qualities and consider the stone as a singular treasure from nature – each as distinctive as a fingerprint.
