Queen Letizia has her pick of the Spanish royal jewellery collection, but she wore a very special piece to host a reception for the Diplomatic Corps at Zarzuela Palace on Wednesday.
The royal, 51, teamed her navy blue gown with a diamond and sapphire necklace with a teardrop pearl and a matching bracelet.
The set is sentimental to Letizia as she was gifted the jewels from her in-laws, former King Juan Carlos I and Queen Sofia upon her engagement to then Prince Felipe in 2003.
According to the Spanish Royal Jewels Instagram account, Queen Sofia told author Pilar Urbano in her 2010 book La Reina Muy de Cerca that the necklace was a gift from her own wedding to Juan Carlos in 1962.
Sofia has worn the necklace in public on several occasions, but Letizia has only worn the necklace and bracelet together once, at a gala dinner on the eve of the royal wedding in 2014.
It's fitting that Letizia has chosen to bring the jewels back as she will celebrate her 20th wedding anniversary with Felipe on 22 May 2004.
