Beautiful silver cz earrings

Gorgeous earrings. NEW earrings that have not been worn. They are silver although they are not marked. I acid tested them, and also wore them for several days with no irritation. Anything other than gold or silver irritates my ears and causes allergic reaction, even earrings labeled hypoallergenic and for sensitive ears. These didn't cause any problems, definitely nickel-free. Approximately 1/3" stone.
