OverviewCutColourClarityCarat Cut, Colour, Clarity and Carat are the worldwide characteristics used to classify the rarity, quality and value of diamonds. Diamonds with the highest combination of 4C ratings are the rarest and most valuable. Our fine white diamonds are hand selected for their exceptional colour and clarity. We always grade to a minimum standard of G/H Colour, SI Clarity. To make your purchase even more special, why not request your diamonds be further upgraded to F/G Colour, VS/VVS Clarity? We only select diamonds free from world-wide conflict.
