Vintage Lisner grape cluster pin brooch

This is a fascinating vintage dimensional pin brooch by Lisner. It features a grape bunch embellished with gorgeous blue Austrian crystal rhinestones on textured silver tone setting. Beautiful swirling design on stem and leaves. Signed on the underside but it's hard to read. In perfect condition. No losses. Just the plating on the pin has been worn off which is not noticeable when you wear it. Great gift idea for your loved one or yourself. Measurements: 2 1/8" tall × 1.5" wide
