Understanding the 4Cs of diamond quality offers valuable insight into the actual quality of the diamond.

Diamond Colour In most diamonds, the term refers to the absence of colour. Less colour in the stone makes it more desirable and valuable. Some differences may not be visible to the naked eye, but affect the quality and price of the stone..

Diamond Clarity assesses the quantity, size, and positioning of internal ‘inclusions’ and external ‘blemishes.’ Ratings range from ‘Flawless,’ with minimal imperfections, to ‘Included,’ which have many imperfections.

 

Diamond Cut does not refer to a diamond’s shape, but to the proportion and arrangement of its facets and the quality of workmanship. The amount of brilliance, sparkle, and fire in a diamond is determined by cut. Grades range from ‘Excellent’ to ‘Poor.’

 

Diamond Carat relates to a diamond’s weight. Typically, the higher the carat weight, the pricier the stone. However, two diamonds of equal carat weight can vary significantly in quality and price when considering the other three Cs.
