happy 9th wedding anniversary, felipe and letizia! 5.22.2004.
Princess Letizia’s wedding gifts→ The unknown tiaras
- Carrera & Carrera tiara, present from the jewellery firm for her wedding
- Ansorena tiara, this present was conceived at the time of her wedding by the late owner of the jewellers and delivered years later.
NOTE: These tiaras have never been seen so it is not known if Princess Letizia’s tiaras actually look like the ones in the photos.
The first one is precious, but I hate pearls on tiaras.
TOKYO —
Crown Prince Naruhito will visit Spain June 10-17 at the invitation of the Spanish government to mark the 400th anniversary of relations between Spain and Japan.
Crown Princess Masako, who accompanied her husband to the investiture of Dutch King Willem-Alexander earlier this month, will not be going, a government official said, according to a TBS report.
During his visit, the crown prince will attend a luncheon with King Juan Carlos and Queen Sofia and a banquet hosted by Crown Prince Felipe and Princess Letizia.This visit seems to follow the pattern of the Prince of Wales and the Duchess of Cornwall’s visit in 2011, the Prince and Princess of Asturias will be the hosts and the King and Queen will only offer a luncheon.

But okay, I love to see Naruhito too.
