Smoky Quartz Cluster on 3 Rings are 18K gold earrings with faceted smoky quartz and a semiprecious bead cluster (tanzanite, sapphire, apatite, etc.). These fun dangles can be worn on Dora Winchester Hinged Hoops, but the default is on French wires. If you're adding to your dangle collection, the dangles can be purchased alone. The standard size of Dora Winchester Hinged Hoops is 10mm, but let us know if you'd like a custom size.
