I made these necklaces using delicate gold 925 sterling silver plated chain. The pendants are scallop shape iridescent white Mother of Pearl shell with turquoise, rose pink or blue quartz centers and wrapped in golden brass. All connecting rings are 18k gold plated. * Your purchase will arrive in pretty packaging CARE INSTRUCTIONS FOR PEARLS: To keep pearls radiant, follow the "last on, first off" ruleāput them on after makeup and perfume to avoid chemical damage. Gently wipe them with a soft cloth after each wear to remove oils and perspiration. Store them separately in soft, breathable pouches to prevent scratches and dehydration.
