Goldbug Collection’s Freshwater Pearl Toggle Necklace features baroque freshwater pearls, a toggle that opens for charms, a lobster clasp, and a 2-inch extender chain. Gold-Plated Brass Pearls: 9.5-10.5 mm Length: 16" with 2" extender Care: To ensure a longer life for your Goldbug pieces, please do not shower, swim, or sleep while wearing them, and keep them away from sunscreens, lotions, and perfumes. To clean your pieces, rinse with warm water and a gentle soap. Like our bug friends, sadly, costume jewelry doesn't live forever! Charms and pendants are sold separately.
