I love this necklace so much! The chain is made of black spinel gems on oxidized sterling silver wire. The charm is a gorgeous quartz crystal encased with 18k gold vermeil and tiny white topaz details. Sparkle Galore! Then hanging from the charm are three black spinel gems bezel set in oxidized sterling silver. It's simply stunning on. It hangs approximately 16" but has an extension chain in the back for some extra length.
