I made these necklaces using delicate gold 925 sterling silver chain or 925 sterling silver chain. Each has an extender making them adjustable from 20"-22" in length and finishes with a tiny teardrop shaped crystal. Each necklace has an AAA grade 8mm purple pearl pendant that hangs from either a 24k gold plated bail, or a sterling silver bail. * Your purchase will arrive in pretty packaging CARE INSTRUCTIONS FOR PEARLS: * To keep pearls lustrous and prevent damage, follow the "last on, first off" ruleāput them on after makeup and hairspray, and remove them first to avoid chemical exposure. Clean gently with a soft cloth after each wear to remove oils and sweat. Store separately in a soft, breathable pouch or box.
