Before a single stone was set in this necklace, Anna Hu poured “10 years of imagining” into its design. Inspired by Claude ­Monet’s Water Lilies paintings, Hu first began conceptualizing the piece when she spent the summer at Monet’s gardens in Giverny, France, as a 20-year-old budding artist. “The images of the pond, the water, and the interplay of light and shade there have been an ­integral part of my memory ever since,” she says. “I wanted to mimic the waves of the water and also create something very feminine and unique.” Hu listened to music by Impressionist composers Ravel and Debussy while designing. The Parisian arts movement “touched my heart,” she says. “It wasn’t science. Like composing, creating the piece just happened naturally.”Stony FacedDeep pink sapphires portraying lilies are surrounded by a host of tsavorites, tourmalines, morganites, alexa
