Princess Maxima's earrings (All but the one on the very left) I feel in love with, and I seriously wished I had them, even if I don't wear them. While, Laurentien's (one of the left) looks very nice, not as great as Maxima's but as good.
Maxima's rings look beautiful. Period.
I love the Dutch tiaras, they have amazing designs, great details, and beautiful stones. The sad part: Not one really sees them because there aren't too many events with Tiaras.
