Vintage earring set with antique brooch

Real freshwater cultured pearl stud earrings. pearls have lovely luster.. A button style...set in beautiful 925 sterling silver. Embellished with little CZs..... Shown here with antique silver tone broach. Because I bought the broach at an antique store over 25 years ago I don't know ìf it is sterling silver. But it has never tarnished. it's shiny.. The stones are secure in the setting. I've not worn it. it has been a collectors item for me.
