I bought this wonderful brooch about 20 years ago at the Delmar show in Delmar California from a local dealer. I do not know where she got it. It is signed on the back ASIN and Sterling and 14 k. It’s quite large not quite 4 inches long and it’s all hand wrought, all formed around a piece diachronic glass or ancient glass maybe the lip of a vase or vessel because it’s curved now of course I’m not sure it’s ancient but it just has that look with the gold and the green, very design has an extra art nouveau look whiplash piece that comes out to frame that is anchored on the side, not a piece of the clasp in the back. I think it’s probably from the 70s possibly the 80s at the very latest and is just so magical renniseance fair
