Madame Belperron frequently worked with 22 karat gold. She loved its uniquely raw texture, referred to as “virgin” gold. Hammering, chiseling and burnishing achieved the antique patina Belperron favoured. Today, Belperron's virgin gold pieces are still hammered, chiseled and burnished by hand. With time and wear, the patina and texture of these jewels only grows richer.
