I think most if not all the stones Willem III (and not Wilhelmina as she was not yet born when Hendrik died) inherited from his brother were used for Emma's Saphire set. The bow brooch of Wilhelmina was not part of her weddingparure but looked well with it. I would not be surprised to find that it was made around the time of her marriage.
--Previous Message-- : Very interesting, Erik. Is this information : based on the style of the brooch? : : I always have doubted that the brooch was : made for Princess Amalia since René Brus : states that Amalia wore Queen Anna's parure : while it only later was altered for Prince : Hendrik's second wife Marie. Yet the drawing : of Marie's parure which Brus adds (although : with incorrect caption, I guess) shows a : parure completely different from the : Orange-Nassau jewels. (Brus, pp. 74-78). : Hendrik died one year later. So the sapphire : jewels as we know them now were most likely : all created for Emma and perhaps Wilhelmina. : : : --Previous Message-- : Indeed, it was made for Wilhelmina. But I : don't know whether a jewel with this : sapphire was broken up for this brooch, or : was lying around in a box. : : :
