Dramatic mid-century star sapphire and diamond brooch

This stunner features a round star sapphire, a gem which has a six-rayed star when seen under a spotlight.  It is the centerpiece of a custom made platinum and diamond brooch, set with 333 diamonds of round, baguette, square and marquise shaped.  We estimate the total weight at 10.27 carats; the sapphire has an estimated weight of 39.27 carats.  The brooch measures about 2” in each dimension.  Definitely red-carpet worthy!
