I made this necklace using bright shiny tarnish resistant 18k gold plated brass flat ball chain that has ornamental end pieces and a 16k gold plated clasp. It has a large pendant made of a double freshwater peach pearls atop an oval abalone shell. The colors are so wonderful. * Your purchase will arrive in pretty packaging CARE INSTRUCTIONS FOR PEARLS: Keep pearls lustrous by following the "last on, first off" rule, applying makeup and perfume before wearing them. Gently wipe with a soft cloth after each use to remove oils/dirt. Store them separately in soft, breathable pouches to prevent scratches and dehydration. Avoid ultrasonic cleaners, harsh chemicals, and extreme humidity.
