The 4 C's - Cut, Clarity, Colour & Carat Weight
Almost every jeweller will be able to tell you about the 4 C's which affect diamond prices. We can tell you about a dozen C's which affect prices.
De Beers who run the Diamond Promotion Service pump out information to all jewellers about their famous 4 C's, the four factors which affect diamond prices. The DPS wants you the consumer to be aware of the different diamond qualities, so that it can get you to pay more money for better quality diamonds.
