Every woman has one – that special accessory which makes you feel a million dollars when you wear it.
Princess Letizia of Spain is no different in that respect, though her favourite piece of jewellery might be a little different from what most of us have in our collection.
The elegant wife of Crown Prince Felipe can boast a platinum and diamond tiara – loaned to her by her mother-in-law Queen Sofia - as her secret style weapon.
Teamed with a sweeping scarlet gown it perfected her look this week for a state dinner honouring Lebanon's President Michel Suleiman at Madrid's Royal Palace.
Royal fans might remember seeing the tiara earlier this year, when Letizia and her husband hosted a white tie dinner for Carla Bruni Sarkozy and the French President Nicolas Sarkozy.
And of course it was the main adornment of her wedding outfit, when she tied the knot with her prince in June 2004.
