A stunning brooch and although unsigned offers enough clues to attribute it to the Regency Company which was in business in New York from the 1940's until the 1970's under the name of Regina Company. They had a reputation for the production of high end jewellery and the use of exquisite faux baroque pearls and quality rhinestones. Here we have a combination of faux baroque pearls, citrine coloured marquis rhinestones and aurora borealis stones all faceted and prong set.  A japanned back and firm roll over safety clasp. In very good condition with a little wear to the back which does not detract at all. A stunning brooch measuring a substantial 6cms x 5cms. Gift boxed by Vintageonline.
