First conceived in London by a Hungarian émigré during the swinging sixties, the princess cut diamond has been popular with trendy types for over 50 years. Join the glittering trend for brilliant square diamonds with this lovely Princess Cut 0.50 total carat weight Diamond Cluster Engagement Ring in 9 carat White Gold: because the princess cut is larger and flatter, it allows for more facets to be cut, which then bring greater sparkle. Carat-for-carat, princess cut diamonds are some of the best value in the jewellery industry, as less rough diamond is wasted during the cutting process, while none of the beauty, grace, or carat weight of the diamond are compromised.
