The most beautiful piece in Buccellati's Opera collection, the Opera Tulle heart-shaped openwork diamond necklace—the diamond-studded heart in the center is dazzling, perfectly complementing Buccellati's exquisite openwork technique. It's truly stunning, both vintage and unique. Every Buccellati piece is handcrafted by artisans, resulting in very limited production; it's a technique that other brands struggle to replicate.
