About Catherine Popesco Jewelry: Each Catherine Popesco La Vie Parisienne piece of jewelry is manufactured in France, and rendered from original 200 year old vintage French molds and stampings. They are then hand set with crystals by highly skilled artisans. By following traditional French techniques, Catherine Popesco allows each piece to exhibit the intricate details of these historical designs. Pieces are new, but have a wonderfully romantic vintage feel steeped in the tradition of exquisite craftsmanship. In order to keep your jewelry at its most beautiful, avoid direct contact with water, moisturizing cream or perfume.
