Fine art and antiquities auctioneer Bonhams will be auctioning off “The Marina B Legendary Luxury Jewelry Collection,” the largest and most valuable collection of Marina B jewelry ever to be sold at auction. As the granddaughter of Sotiro Bulgari, founder of Bulgari, Marina B grew up surrounded by some of the world’s most exquisite jewelry and this is reflected in the nine individual lots that will be auctioned off. Among the items to be sold are an exquisite cultured pearl, sapphire, diamond, tourmaline and onyx “Pauline” torque necklace and a magnificent sapphire and diamond “Amelia” necklace and earring suite.
