Which "C" is the most important?
The 4Cs — colour, clarity, cut and carat weight — are the globally accepted standards for assessing the quality of a diamond.
A diamond's quality depends on a combination of all the four "Cs." However, Tiffany & Co. believes the most critical of these is cut. More than any other factor, cut determines the brilliance, fire and overall beauty of your diamond.
