This Weiss signed brooch features mostly keystone shaped and some round chaton clear rhinestones, all prong set in silver tone. This three-dimensional brooch has two layered tiers in a diamond shape. This beautiful, old brooch measures 2.25" inches X 1 3/8" inches. Back of pin is hallmarked "Weiss" without the copyright symbol, dating this piece to before 1955. This rare-to-find piece with keystones is in very good to excellent condition, with some age-appropriate wear to the back, but the stones are all clear. Elegant piece!
