1970s Diamond Floral Sunburst Brooch, 18K Yellow Gold and Platinum

A trio of gold sunburst blooms opens across this 1970s brooch, each ray tipped in pavé diamonds so the whole flowerhead reads as one continuous starburst rather than a set of separate petals. The centers are worked in a fine granulated texture, a warmer rose-toned gold against the brighter yellow of the petals, giving the illusion of pollen-dusted stamens at close range. Diamond-set leaves in platinum break up the gold with a cooler, brighter line down the stem, a deliberate two-tone contrast typical of 1970s floral brooches built for scale and presence rather than subtlety. In total, 127 round brilliant-cut diamonds trace every ray and leaf, F-G color, totaling 4.50 carats of dense, continuous sparkle. At 70mm long, the brooch has real weight and reach; this sits on a lapel or wide scarf, not a blouse collar. Excellent vintage condition, no visible wear, all stones secure, pin mechanism functions smoothly. Stamped 18K.
