Below are two additional photos which I found some time ago but never got around to posting.
A photo showing the couple arriving at the Empire Ball in 1935
I think that Princess Marina may have worn the tiara to the Hampden House Ball (a coronation ball) in 1937 -- but I am not 100% sure. The tiara definitely isn't the City of London fringe tiara or the diamond and pearl snake tiara.
What do others think?
