It is quite mind boggling how many star elements Dutch Royal family owns...but at least we can agree to the fact that the stars on Maxima's tiara are easily identifiable (at least to me) on Queen Juliana's sash...
The mystery is surely those "3" stars that Maxima recently wore...we have only seen them as brooch(s) or as a choker on Laurentine...and just one...
And we can also agree on the fact that the stars that Queen Beatrix is always seems to wear are the ones from Queen Wilhelmina's diamond tiara...they are the most recognizable stars by having huge diamonds in the center and graduated round diamonds on the spikes
