The second day of King Harald V and Queen Sonja of Norway’s joint birthday celebrations included a black-tie gala at the Opera House in Oslo. Even without tiaras, we saw some major jewels on display. Here’s a look at what the Scandinavian royals wore; we’ll recap the rest of the royal jewels in our next post!

After last night’s emerald spectacular, Queen Sonja chose quieter pearls for the gala: earrings, necklace, and bracelet.

Her white cape-coat covered a vibrant blue gown.

Crown Princess Mette-Marit of Norway wore the same diamond pendant earrings she wore last night, but this time she added her faceted red gemstone (ruby?) drops instead of pearls.

The deep red earrings were a contrast to her navy blue gown. (Also, note Crown Prince Haakon’s newly-shaven face — did you know he shaved off the beard last night during the dinner? I’m still so perplexed. We’ve been discussing the possibilities on my Twitter feed…)

Princess Martha Louise of Norway was radiant in a fun pair of multi-gem pendant earrings.

The earrings picked up on the various colors in her bright pastel gown.

Like her sister-in-law, Princess Astrid chose pearls for the opera house gala.

I’m pretty intrigued by that gem-set golden bangle on Astrid’s right wrist.

Here’s a look at Astrid’s flower-festooned pink dress. (Astrid’s escorted here by a lady-in-waiting; note the red badge she wears.)

Queen Silvia bundled up against the persistent rain, but we got a glimpse of the family’s diamond floral earrings and a diamond riviere.

Her dark patterned dress peeked out as she and King Carl XVI Gustaf arrived at the Opera House.

Crown Princess Victoria made an ill-advised earring selection for the gala, selecting a pair of exaggerated tassels. The earrings clashed with the high neckline of her floral gown. I think these earrings would be more interesting with an off-the-shoulder gown. (And without the focus-pulling flower in her hair.)

Victoria also wore a few bracelets, including a large silver cuff.

Here’s a better look at Victoria’s entire ensemble.

Princess Sofia of Sweden chose delicate gold pendant earrings, sweeping her hair aside to offer us a clearer view of the jewels.

She matched her gold earrings to a golden clutch bag.

Queen Margrethe II of Denmark was also wrapped up in a cloak, but we can see Queen Alexandra’s sapphire demi-parure peeking through here.

Here we get a view of the necklace, too. I think she’s wearing the same gown and jewels that she chose for another recent gala in Norway.

Crown Princess Mary brought along some glitter from Denmark, wearing diamond fringe earrings with a floral motif.

She also wore a stunner of a sapphire and diamond ring on her right hand.

The bright blue gemstone in the ring picked up the blue hues in her floral gown.

Prince Joachim and Princess Marie joined the royal pack for tonight’s gala. She kept her jewelry fairly simple, wearing a pendant necklace with a blue (sapphire?) stone and glittering earrings.

Her gown, also on the simple side, looked like one of the most comfortable of the night.

King Harald V and Queen Sonja of Norway both turn 80 this year, so they decided to combine their celebrations into one super-sized bash this weekend in Oslo. Tonight, things got very sparkly at a white-tie birthday dinner. Here’s the first of two posts focusing on the glittering tiaras worn this evening!

Queen Sonja wore pieces from the grandest parure in the Norwegian vaults: the family’s emerald set. Unfortunately, the green in these jewels isn’t super pleasant with the bright red sash of the Order of St. Olav or the red ribbon of King Harald’s family order.

But the emeralds themselves are exquisite. Sonja wore the tiara, earrings, necklace, and brooch from the parure.

Unfortunately, the acid-green hue of Sonja’s dress didn’t work with either the emeralds or the order sash, in my opinion.

The emeralds were a slam-dunk guess for tonight’s dinner, but we got a big tiara surprise from Crown Princess Mette-Marit of Norway. She wore Queen Maud’s Vifte Tiara as a diadem for the first time, pairing it with her interchangeable drop earrings, this time hung with pearls.

Mette-Marit has worn the Vifte Tiara in public only once before: at her pre-wedding gala, when she wore it as a necklace. This time, she placed the teeny tiara in the back of her hair, creating a halo-like effect from the front.

Mette-Marit wore both the sash of the Order of St. Olav and King Harald’s family order with her gown. She was escorted into the dinner by King Carl XVI Gustaf of Sweden.

Princess Martha Louise of Norway wore a mish-mash of jewels from her personal collection. Her tiara, King Olav’s Gift Tiara, was an 18th birthday gift from her grandfather. She paired it with dramatic dimaond hoop earrings, a diamond brooch, and the lovely necklace she wore at the wedding of Princess Madeleine of Sweden. The recently-separated princess also wore a major cluster ring on her left hand.

Martha Louise, who was escorted by King Philippe of Belgium (her second cousin), wore the sash of the Order of St. Olav and her father’s family order.

King Harald’s sister, Princess Astrid, wore her grandest suite of jewelry: the diamond and turquoise parure that once belonged to Queen Alexandra of the United Kingdom. She secured her order sash with a diamond and pearl bow brooch.

Her star-spangled gown was festooned with the sash of the Order of St. Olav and the family orders of King Haakon VII (her grandfather), King Olav V (her father), and King Harald V (her brother). She was escorted by a smiling Prince Nikolaos of Greece and Denmark.

From Norway’s neighboring nation, Queen Silvia of Sweden wore the tiara, earrings, and brooch from the grand Leuchtenberg Sapphire Parure. (The sapphires were once a part of the same royal jewel collection as Queen Sonja’s emeralds.)

Silvia, who was escorted by the President of Finland, wore the sash of the Order of St. Olav and the family order of her husband, King Carl XVI Gustaf.

Crown Princess Victoria of Sweden wore one of her favorite tiaras: the Baden Fringe. She paired it with the family’s diamond epaulette earrings and the diamond lozenge brooch from the family vault. She also wore the sash of the Order of St. Olav and her father’s family order.

Princess Sofia of Sweden was resplendent in the family’s tall Diamond Six-Button Tiara. She paired the diadem with the diamond earrings from Queen Josefina’s stomacher (also worn on her wedding day) and a small, round diamond brooch.

Sofia, escorted by Bernhard Mach, doesn’t have a Norwegian order, so she wore the sash of her highest Swedish order, the Order of the Seraphim. She also wore her father-in-law’s family order.

Queen Margrethe II of Denmark made a splash in major diamonds at the birthday dinner, wearing the flexible Danish Floral Aigrette.

Here’s another view of the jewels. She wore elaborate dimaond earrings, a diamond riviere, and a diamond bow brooch with the aigrette.

Margrethe wore the sash of the Order of St. Olav, plus the family orders of King Christian X (her grandfather) and King Frederik IX (her father). She was escorted by Crown Prince Haakon of Norway.

Denmark was also represented at this dinner by Crown Princess Mary. She wore her convertible Edwardian Tiara with the new earrings recently created to match the piece. She also secured her sash with her small round diamond brooch.

Mary, who was escorted by Prince Albert II of Monaco, wore the sash of the Order of St. Olav and her mother-in-law’s family order.
