I've just found this stunning picture of Queen Mary (possibly when still Duchess of York): http://antique-royals.tumblr.com/post/110910001428/queen-mary-of-united-kingdom I can recognize that she's wearing: -the Warwick sun brooch (later dismantled) as an hair ornament -her pearl and diamond choker (now with the Gloucesters) -some other pearl strands (one with a pendant drop pearl) -pearl and diamond earrings -various bracelets but I can't recognize the corsage brooch she's wearing, I think I've never seen it before. It seems to be made with pearls (both round and drops) and diamonds.
