This 1950s vintage pinwheel brooch will have you looking brilliant in blue. It features pear and round-cut pale blue Aurora Borealis Swarovski crystals. It closes with a safety-catch pin, with a Trifari signature. Trifari created some of the most desirable costume jewellery of the twentieth century, many of its designers having trained at Cartier. The company patented its own non-tarnish metal, calling it Trifanium and was first to copyright its jewellery designs
