I happened to notice this small gold brooch seen here midway down HM's sash (on the left). It does not show very well but it is more noticeable as shown on the cover of the 1987 edition of Field's book (the paperback version). It almost looks like part of her dress but I am pretty sure it is not. It looks to be a round brooch with a cross and filigree or cut-out work. Does anyone know anything more about this?
