If a four-leaf clover is good luck, surely one made of gold is extra fortuitous. That’s the promise of this Vintage Alhambra bracelet from Van Cleef & Arpels ($7350), which features five gold clovers. Part of the collection celebrating the 50th anniversary of the first Alhambra necklace, the bracelet is replete with guilloché, where lines are etched on the metal to create a chic, subtle pattern. Each motif is decorated with a series of golden beads and finished with a central dot of gold. Visit vancleefarpels.com.
