Despite its beauty, this tiara’s provenance is truly unknown. Princess Anne of Denmark wore this tiara to her wedding; the central cluster of diamonds is undoubtedly worth tens of thousands of dollars. The tiara is probably of Swedish or Danish heritage, even though the necklace that goes with it was a gift from Queen Elizabeth and King George VI.

Princess Ingeborg of Sweden, Prince George’s grandmother, might be the source of this tiara. It is possible that Ingeborg gave Princess Anne a tiara for her own wedding, as she had given one to her sister-in-law for her 1949 nuptials.
