Mid-century Sterling Splatter Enamel Clip Earrings Handmade Artist Signed RAYA

These are so artistic. Large sterling and splatter enamel earrings signed Raya Sterling Handmade. A dark blue background has streaks of green red and light blue . They are abstract in shape, not quite fully round . They are rather heavy because of the thick enamel. But, they have an ingenious clip. You push the clip in, slide it on your earlobe and the weight and pull tighten the clip on your lobe. it's actually quite comfortable. Unable to find anything on the artist. I suspect they are from the 1970s. The enamel is a little rough on the edges (see pic) I believe from the manufacturing process. Still, in very good condition. 2 1/2 inch long.
