These earrings are a brilliant purple amethyst accented with a crust of diamonds and sapphires and iolites hanging softly from oxidized sterling. Alexis Bittar has always made great fun and enormously elegant jewelry from lucite, semi-precious stones and metals like rhodium, but a couple of years ago he added a fine line of gold and silver. The pieces are delicate and colorful. These earrings sparkle and glow like purple stars in a Van Gogh night. Save them for a lacy long-dress occasion—or wear them around the house with nothing else.
