Van Cleef & Arpels is a jewelry house that creates pieces made with precious materials and metals fulfilling the most stringent selection criteria. The materials used in their jewelry pieces depend on their properties, and certain materials require specific care. For example, the Alhambra collection is made of materials such as Sèvres porcelain, coral, rose gold, yellow gold, white gold, platinum, and mother-of-pearl.
Van Cleef & Arpels jewelry pieces are marked with a trademark, serial number, and metal hallmark. The brand stamping has varied over the years, but it should read either "Van Cleef & Arpels" or "VCA". The jewelry house uses only 18 karat gold, so each piece should be marked "750" or "Au750". The signature of Van Cleef & Arpels is showcased as "VCA" on a tag close to the male end of the clasp or on the side of a motif adjacent to the clasp.
