In Japan, Lucie Heskett-Brem would be a national treasure: a master craftsman in precious metal who makes each link of each jewel by hand, in perfect proportion. Here, her reversible rainbow sapphire necklace graduates from a 15mm center flower link set with a pale blue sapphire to a 14mm flower at back. Each link is handmade by the artist in sterling silver, set with multicolored sapphires in pink, blue and lavender, and linked by 20K figure eight links. The 18" necklace reverses to be worn without gems, with 20K yellow gold flower centers. Also available in a petite link version.
