The tiara is by Ansorena and it does exist, because Ansorena talked about it to the press. I clearly remember reading the article back in 2010. IIRC the person from Ansorena talked about how his late father had wanted to create a tiara for Dona Letizia, and they wanted to continue the tradition of making tiaras for the Spanish Queens. Something like that. Imo, they deliberately avoided to tell clearly whether it was payed for by Felipe or if it was a gift from Ansorena. Also, they had tiaras in very similar designs for sale at their homepage.
