Winifred Mason Chenet is considered an important part of modernist art/jewelry movement in N. From what I have read on-line about her. The earrings are vintage and therefore do show some wear and some discoloration on the backs.Please see the pictures and to note is the last picture does have some shadowing from the camera on the earring back which makes the discoloration look enhanced.
