The Gold Constellation Necklace 3mm by James Oro is a 20" tennis-style necklace for men and women, with seven different stone shapes hand-set in continuous sequence. The slimmer 3mm width is easy to wear every day, alone or layered, and the warm gold adds light to earth tones, black and cream, from casual days to events. It’s crafted from a nickel-free copper and zinc alloy with 18K gold PVD plating, and a custom oval double-push clasp keeps it secure. Pair it with the matching Constellation 3mm Bracelet for a complete set.
