Rhinestone Set Pear Shaped Vintage Brooch

Recently arrived from USA...a large pear shaped brooch set with rhinestones, set in gold tone metal.  A season of fruitfulness and new growth...the symbolism of brooches. It is substantial in size at 7cms length, and 4cms across at the widest point. There is a signature to the back "Stanley" which is unknown to me, along with a copyright sympol.  There is a firm roll over safety catch.  In good vintage condition, gift boxed by Vintageonline.
