Mother of Pearl & Marcasite Earrings

Lovely mother of pearl discs, about 1/2" diameter with 925 sterling swirl featuring tiny marcasite stones. Silver tone stud earring backs. Top of stud to bottom of pearl disc measures about 1". One of the tiny marcasite stones is missing... Can't see it unless you inspect it very closely, but full disclosure here! Otherwise excellent condition. Comes from nonsmoking home and I ship quickly!
