The necklace is crafted of 18 karat yellow gold and features ten malachite clover motifs framed in beaded details. PLEASE NOTE: This piece has a clasp that is no longer in production. Contemporary Alhambra pieces have the Maison Van Cleef and Arpels logo on them. The logo is absent due to age and the iterative jewelry design process and does not affect authenticity.
