I made this necklace using delicate gold 925 sterling silver plated chain with an extender making it adjustable from 20"-22" in length. The pendant is a white freshwater teardrop shape natural pearl with a 16k gold plated flower cap. 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.
