Vintage Rare Anne Klein Lion Head Logo Crescent Shaped Earrings

Very Rare to find this vintage Anne Klein Lion Head Logo crescent shaped post earrings. I got these at an antique market in the 1990s and with all the chips shown in the photos. Loved the size but these but they ended up on display with other earrings in a mirrored cabinet. They are heavy. The surface is white enamel but unsure the metal material. I believe the side with an etched line in the lion face is the side you wear facing out. Check out condition in photos.
