At the heart of this ivy-inspired necklace is a show-stopping leaf formed from diamond-set white gold and a 40.70ct Australian black opal. The opal leaf actually be detached from the design and worn independently as a brooch. The rest of the Alessio Boschi necklace is a weaving combination of gemstones - white diamonds, blue sapphires, purple sapphires, tsavorites, and hrome diopsite - set into white gold. Adding an element of movement to the design are more than 30 briolette-cut tsavorites that tremble and roll elegantly when the necklace is worn. The Ivy necklace also has a matching set of earrings.
