Large 1940's Vintage Retro Brooch With Sapphire Blue Rhinestone

A huge brooch measuring 10.5cms down and 6cms across, geometric in design and from the 1940's. It is gold tone metal with four large deep sapphire blue rhinestones. There is a little wear to the metal commensurate with its almost 80 years of age. Nothing that detracts when worn.  It is a great statement piece. Recently arrived from USA. A rare find, and gift boxed by Vintageonline.
