Vintage Grape Gold Tone Demi Parure Set Post Stud Earrings + Brooch

This was a set I put together over the years as I don’t like clip-on earrings. The grape brooch is signed at the back but I can’t make out the name (Peri?). The earrings probably started as clip-ons but were (mercifully) converted to posts. One earring has lost a pearl but everything else seems intact. There is some gold loss due to age in the earrings; the c-clasp brooch looks to be in fine shape. Measurements in photos.
