Aurora Borealis Rhinestone 60's Designer Brooch

A gorgeous brooch signed to the back "Tammy Jewels" which I resarched to find - Jean Barnes opened Tammy Jewels in 1961, a home selling business based in Indianapolis, Indiana, USA, and later the ranges were also sold in boutique jewellery stores.  She actually on sold the business which eventually closed in 1986. This is a recent acquisition from USA and it has been kept in perfect condition - obviously boxed away. It has a free form ribbon design with five rows of small aurora borealis rhinestones reflecting beautifully shades of blue and gold. Measurement of the brooch is 7cms x 4.5cms. There are 7 narrow baquette shaped aurora borealis stones across the centre. All set in silver tone metal with a firm roll over safety clasp to the back.  Perfection, and gift boxed by Vintationline.
