Pearl, Silver Marcasite Necklace & Earring Set

Still in the box! The 7mm pearl hangs below a 1/4-inch marcasite flower cluster, There is a 16-inch sterling silver chain marked 925 Italy on the clasp, with the hallmark GM. The back of the pendant is also marked 925. The matching post earrings also have 7mm pearls. The earring backs are marked sterling 925, and have safety plugs for added security. I only took it out of the box to measure the chain and check the markings. NS-37
