Vintage Lisner Corn Stalk Rhinestone Flower Brooch

This vintage brooch is signed Lisner. I'm not sure if it is supposed to be a clear rhinestone ear of corn in it's husk, or if it is a flower....you make the call! The rhinestones are sparkly and the leaves or husk is bright gold tone. It measures 3" x 1 1/4" and is in excellent condition.
