18kt yellow Vintage Van Cleef & Arpels fluted gold "Alhambra" earrings. Van Cleef & Arpels was founded in 1906 in Paris. The signature four-leaf clover motif was launched in 1968. The Alhambra collection was inspired by Moorish quatrefoil architecture and the personal good-luck habits of Jacques Arpels, who frequently gifted wild four-leaf clovers.
