Diamond buyers/ brokers then move the gem-quality stones to cutting operations, where the raw stones are evaluated for colour and clarity. Plans are developed to highlight the colour and clarity of each individual stone while preserving the highest carat weight. (About 60% of a raw stone's weight is lost in the cutting process.) Then the stones are cut and polished, and sold to brokers/jewelers who mount the finished diamonds into jewelry.
