Nr. 8 can also be worn as a necklacehttp://www.royal-magazin.de/niederlande/maxima-tiara.htm
No 11+12 is nice, because you can wear it with and without the pearls and it looks totally different. http://www.royaldutchjewels.nl/Antique_Pearl_Tiara.htmLaurel Wreath Tiara
The oldest tiara in the Royal Families collection, the Laurel Wreath Tiara, dates back to the 1800s. Some believe it belonged to Princess Louise, a sister of King Willem I, while others say it was purchased by Queen Juliana in 1956 for Princess Beatrix's 18th birthday. The tiara is made entirely of diamonds and resembles a Grecian headpiece. Beatrix wore the tiara frequently when she was young. Her sister Princess Margriet wore it on many occasion. The last person who has been seen wearing this tiara was Princess Laurentien.
but I guess my fave tiara is this one:
Ornate Pearl Tiara aka Württemberg tiara
Queen Sophie, born princess of Württemberg, received the diamond and pearl tiara as a wedding present from her father, König Wilhelm I von Württemberg.
Queen Beatrix chose this striking tiara, in it's most elaborate setting, at her 1966 wedding to Claus Von Amsberg. In the 1970's she has worn the tiara with only the lower row of drop pearls. Years later, in 1982, she would wear the most elaborate setting once more for a State Banquet in Great Britain . Since then she has worn the tiara in a more simple setting.
