Vibrant Red Aurora Borealis marquis cuts fill in most of this tree or plant motif brooch. The carved or molded glass stones resemble acorns or buds. Three of these stones are encircled with a row clear chatons in an open work design, it's quite a delicate addition. This is an exceptionally well made piece that positively begs for attention. 2 3/4 x 2 1/4 inches. Ca., 1950's and in very good condition.
