Regardless, we do know that the tiara was worn in a portrait by Margrethe's mother, Ingrid, when she was a Swedish princess. That portrait has been a source of some confusion; although Ingrid wears a veil, she is wearing Swedish court dress. The portrait, which is featured in Jensen's book on the Danish royal family's jewels, is dated to 1928, the first year that Ingrid participated in the opening of parliament in Sweden. The veil she wears was inherited from her mother, just as the turquoise bandeau was. (In the portrait, Ingrid also wears the Devonshire Brooch, which features a cabochon turquoise surrounded by four diamonds; this was a wedding present to her mother in 1905.)

The tiara has also been lent to others on various occasions. It was worn by Crown Princess Martha of Norway (mother of the current king) at the wedding of her sister, Astrid, to King Leopold III of Belgium in 1926. She's the person marked with the yellow #1 in the group photo above. On that occasion, it must have been Martha's cousin, Ingrid, doing the lending. Jensen notes that, at some point, the tiara was also worn by at least one of the Haga princesses (Ingrid's nieces -- the four sisters of King Carl XVI Gustaf of Sweden).
In later years, the tiara has been worn by Madeleine Tengbom (maternal grandmother of Prince Richard of Sayn-Wittgenstein-Berleburg, the husband of Princess Benedikte of Denmark) at her grandson's wedding, by both of Princess Benedikte's daughters, and by Princess Theodora of Greece and Denmark at her aunt Margrethe's Ruby Jubilee in 2012.
