Kenneth Jay Lane Vintage Black Enamel Earrings

These vintage earrings by Kenneth Jay Lane are made of a gold tone metal and black enamel. They feature four white faceted crystal stones in different shapes, bordered by a thin layer of gold. The earrings have clip on backs that are stamped (C) KJL and have their original white padding. I've seen these earrings made with different coloured enamel and stones, but I haven't seen this particular combo. To me it seems like some of the stones are yellowing but I don't know if that's intentional or not. Dimensions: 22mm x 22mm Weight: 16.06g
