Our first tiara contest of the week kicks off now!

This detailed diamond floral tiara originally belonged to Princess Dagmar of Denmark, a sister of King Christian X (and King Haakon VII of Norway). The tiara was later passed on to Queen Margrethe II, who offered it as a long-term loan to her daughter-in-law, Princess Marie, in 2008. Since then, it has been Marie’s primary tiara, worn for all sorts of gala occasions.

This delicate floral tiara, made in the nineteenth century, was a wedding present given to Lady Elizabeth Bowes-Lyon (better known to us as the Queen Mother) by her father, the Earl of Strathmore, in 1923. She loved to wear the tiara across her forehead in trendy 1920s style, but it’s not been worn by any other member of the family, and it’s still in the vaults today.
