Created in 1968, the Van Cleef & Arpels Alhambra collection is one of the rare fine jewellery lines that consistently retains 85–100% of its value on the secondary market, with some rare-stone pieces actually appreciating over time. Its quatrefoil motif in gold edged with gold beads has become the ultimate talisman of luck and elegance : not a seasonal accessory, but a timeless investment piece designed to be handed down through generations. In 2026, retail prices have increased by over 20% in three years, making authenticated pre-owned pieces increasingly attractive for informed buyers.
