Letizia never wears a ring on her ring finger, but she does wear other rings. I wonder why? I'm surprised she doesn't even wear a simple like her husband.
I remember reading that it has something to do with her hand hurting if she shakes a lot of hands while she wears it, since in Spain they wear the rings on their right hand. Also was there some shady provenance with the ring's origin/funding? Not her fault, of course, but not the best optics?
