Handmade Giant Sterling Silver Plated Cicada Earrings // Made in USA // Silver Plated Ear Wires // Bug Insect Entomologist Entomology. Giant sterling silver-plated cicada stampings drop from lead and nickel-free silver-plated ear wires. Size of stampings: 31mm x 49mm Please note, because of the design of kidney ear wires, I always recommend storing them with the clasp closed so that the charm or pendant does not slide off.
