Back in 2010, some European royals had travel plans for Queen Margrethe’s 70th birthday postponed because of the Icelandic volcanic eruptions, but others were able to make it, including a trio from Sweden! Here’s a look at the jewels worn by Crown Princess Victoria for the concert gala.

Victoria was escorted by two handsome men as she arrived at the gala: her brother, Prince Carl Philip of Sweden, and her fiance, Daniel Westling. She and Daniel had announced their engagement more than a year earlier, in February 2009. Their wedding was held a few months later, in June 2010.

For the concert, Victoria wore the Swedish Four-Button Tiara. The tiara features four antique diamond rosettes set on a simple frame. It was assembled in the 1950s, using four matched diamond buttons, for the use of Victoria’s aunts, the Haga Princesses.

With the tiara, Victoria wore a pair of small diamond drop earrings with major history. These were originally drops on Queen Josefina’s Diamond Stomacher, which is now arranged for wear as a necklace.

She also added a lovely long strand of pearls.

Victoria’s diamond engagement ring was visible on her left hand. She wore several pieces of chivalric insignia, too: the sash and star of the Order of the Elephant (her highest Danish order), the star of the Order of the Seraphim (her highest Swedish order), and her father’s Royal Family Order.
