YVONNE LÉON Minaudière Coeur 9- and 18-karat gold, agate and diamond necklace

Yvonne Léon's necklace is strung with a heart-shaped pendant that's inspired by glamorous, vintage minaudières - the agate-tipped prongs at the top open just like those on the handbags. It's handcrafted from 9- and 18-karat gold and set with light-catching diamonds, totalling 0.67-carats.
