Vintage 1980's genuine apple sponge coral inlay lucite necklace. The large center pendant measures 4" across. Most likely made by Lee Sands, but it is unmarked.
Reminds me of a butterfly wing. The necklace measures 9" from the pendant edge to the top on each side. Hook closure. Great shape. There is a little raised mark on the back. See 4th photo. No big whoop!
I have another apple coral butterfly style necklace listed which differs in style, so you may want to check that one out as well.
