Vintage 80's enamel and stone earrings lot, some signed siegfried 1989

Great lot of 80's enameled earrings, Ive had them for a long time, some are enameled with acrylic stones, the clip pair almost looks like stained glass with possibly some gemstone chips in there, hoops are sequins and beads I think, purple artistic pair has a matching pin and those are signed siegfried 1989 , I think thats the name but I don't know for sure. They could use new backs and a cleaning but I'm selling as is, I do not want to damage them. Feel free to ask questions, thanks for looking! These are all pretty large as well.
