The listing, SITI Cloisonne Vintage Earrings has ended.
SITI makes a lot of Cloisonne jewelry and is the maker of these pierced earrings, as indicated by the mark. I think I am having lighting issues when taking my pics, so I will describe. The edge on 1 side is black, the flowers purple, leaves green and gold cloisonne around the edges of the black and red areas as well as the leaves and flowers. they are really nice-looking. Not sure of the age, but they are not recent. The backs were missing so I just put a pair of silver backs on these, just to have something there. Sorry, I do not have any new gold backs.
