Couronne Bleue crowns the hand with a pear-cut lab-grown diamond in Fancy Vivid Blue, held high in three platinum prongs. Leaves paved with white diamonds fan out on either side like a tiara, while two diamond-set rows of the band sweep in and meet in a soft V beneath the stone.

A pear-cut blue lab-grown diamond sits high in three platinum prongs, its tip guarded by a V-prong. Six leaves paved with white diamonds rise around it like a tiara, and the band splits into two diamond pavé rows that meet in a V beneath the stone before flowing into a smooth, comfortable shank.

Care

Platinum is dense and durable, and diamonds are the hardest gem there is, but the raised pear setting, diamond-paved leaves and split band deserve a gentle touch. Soak in warm soapy water and clean around the prongs and pavé with a soft brush, then rinse and dry. Take it off for sport, gym or heavy work, store it on its own in a soft pouch so the crown is not knocked, and have the prongs and pavé diamonds checked once a year. Platinum develops a soft patina over time; it can be re-polished whenever you like.
