While Marie wore white for the Queen’s birthday dinner, she chose a bright red gown for the concert gala. (White and red are Denmark’s national colors — Crown Princess Mary also alternated the two colors during these events!)

Marie accessorized the red dress with classic diamond jewels.

It was another outing for Princess Marie’s primary tiara: Princess Dagmar’s Floral Tiara. The piece was her wedding tiara, and although she has access to two other sparklers now, she still primarily wears this diamond floral tiara.

She paired the tiara with simple diamond stud earrings…

… and her small diamond flower brooch, which she used to secure the sash of the Order of the Elephant. (Back in 2010, Marie didn’t yet have Queen Margrethe’s Royal Family Order. She does now!)

Marie also wore a stack of gold bangle bracelets on her right arm and wrist, including an intriguing twisted bracelet. The bangles coordinated with the detailed gold clutch she carried.

Our look back at Queen Margrethe’s 70th birthday concert continues with the sparkling jewels worn by her daughter-in-law, Crown Princess Mary of Denmark.

Mary wore a flowing, Grecian-style one-shoulder white gown for the gala in Copenhagen. She accessorized with pieces from her most important jewelry set: the Danish rubies.

At this concert gala, Mary debuted the renovated version of the grand ruby parure. The tiara had been slightly reconfigured to better fit her head, and the earrings were adjusted to be worn at various lengths and with various pendants — here, for example, with pearl drops.

Here’s another angle that shows the shape of the renovated tiara. The changes Mary made were controversial with some who believed that she shouldn’t have altered such a famous piece — but it’s worth remembering that the previous wearer, Queen Ingrid, made substantial changes to the tiara as well, transforming it from a simple bandeau to the wreath we’re familiar with today.

Mary also pinned the large corsage brooch from the set to the bodice of her gown…

…and wore the diamond, ruby, and gold bangle, an addition to the parure made by Queen Ingrid, on her left forearm. She stacked a few rings on her right hand as well.

With her gown and jewels, Mary also wore the sash and star of the Order of the Elephant, as well as her mother-in-law’s Royal Family Order.

Here’s one more look at Mary’s jewels from the event. What do you think: should she have renovated the set, or worn it just as Queen Ingrid did?
