Representing Belgium at the wedding, the Duchess of Brabant (now Queen Mathilde) wore her laurel wreath tiara, plus drop earrings with pale stones, a diamond bracelet, and a diamond floral necklace. She also wore the second-highest ranking Swedish order, the Order of the Polar Star.
Princess Claire of Belgium wore her diamond and pearl tiara at the wedding, plus diamond and pearl drop earrings.
A third Belgian princess, Astrid, wore the Savoy-Aosta Tiara from her husband’s family’s collection, pairing it with sparkling earrings and the Order of the Polar Star.
Beatrix of the Netherlands, still the country’s reigning queen in 2010, wore the gorgeous tiara from the Mellerio Ruby Parure to her goddaughter’s wedding. She also wore ruby and diamond earrings, a diamond riviere, and the Order of the Seraphim.
Maxima (then Princess, now Queen of the Netherlands) shone in diamonds at the wedding, wearing the Dutch Diamond Bandeau, a glittering diamond riviere, diamond drop earrings, and some of Queen Emma’s diamond stars on the sash of the Order of the Polar Star.
She also secured the back of her order sash with a diamond brooch and two diamond bracelets, the Dutch Diamond Star Bracelet and her own diamond wedding bracelet, as well as Queen Juliana’s diamond watch (on her left wrist).
Princess Catharina-Amalia of the Netherlands (now the Princess of Orange) is one of Crown Princess Victoria’s godchildren, so she was among the royal wedding party. Before the ceremony, she posed with her parents, Willem-Alexander and Maxima.
Princess Laurentien, another of Beatrix’s daughters-in-law, wore Queen Emma’s Diamond Tiara at the wedding with its ruby center stone. She also wore diamond earrings from the Dutch royal collection.
Laurentien doesn’t have a Swedish order, so she wore her highest Dutch order: the Order of the House of Orange. She secured the sash with a diamond brooch. This photo also gives you a good view of her diamond bracelet, one of the set made out of Queen Juliana’s large Dutch East Indies Bracelet.
Princess Mabel of the Netherlands, Beatrix’s third daughter-in-law, wore her wedding tiara to this royal wedding. The tiara was made in 1888 by Mellerio; originally the top row of gemstones was set with chocolate diamonds, but those have since been removed and replaced. The replacement stones are reportedly the top row of diamonds from the family’s sapphire tiara. She also wore large diamond pendant earrings.
Mabel doesn’t have any royal orders, hence the lack of a sash on her gown. Her late husband, Prince Friso, wore the Order of the Polar Star. Sadly, this was one of his last appearances at a major royal event before his skiing accident and his subsequent death. (Also, yes, Mabel’s dress is half skirt, half trousers.)
Grand Duchess Maria Teresa of Luxembourg stole the show at this royal wedding, busting out the enormous Luxembourg Empire Tiara for the evening. She also wore an impressive diamond riviere, pearl drop earrings, and a pearl and diamond brooch that originally belonged to Princess Ingeborg, the wife of Prince Carl of Sweden.
Maria Teresa also wore a diamond bracelet and the Order of the Seraphim.
The Countess of Wessex, representing the Queen, wore her wedding tiara to Victoria’s wedding. (Sophie’s anniversary is also June 19 — rewind to her wedding here!) She also wore a pair of diamond earrings with a coordinating necklace. Sophie has no Swedish order, so she wore her highest British order, the Royal Victorian Order. She secured the sash with the diamond brooch given to her by her husband, the Earl of Wessex, as a first anniversary present.
Sophie also wore a pair of bracelets and her mother-in-law’s family order.
Hereditary Princess Sophie of Liechtenstein wore the family’s gorgeous Habsburg Fringe Tiara at the wedding, plus diamond earrings and a beautiful diamond floral brooch.
Queen Sofia of Spain donned the Mellerio Shell Tiara at the wedding, pairing it with a pearl necklace with a shell-shaped diamond pendant. She’s also wearing the diamond earrings from the joyas de pasar collection.
Sofia secured the sash of the Order of the Seraphim with a diamond fleur-de-lis brooch.
The Princess of Asturias (now Queen Letizia) borrowed her mother-in-law’s diamond floral tiara, pairing it with her own diamond wedding earrings.
Because she has no Swedish orders, Letizia wore her highest Spanish order, the Order of Charles III. At her waist, she secured the order sash with the fleur-de-lis brooch that forms the central element of her new Ansorena tiara.
Infanta Elena of Spain wore the Marichalar Meander Tiara, a piece that was a gift from the family of her former husband. Her small earrings appear to be set with amethysts.
Like Letizia, Elena wore the Order of Charles III with her very Spanish gown.
Infanta Cristina of Spain borrowed the Cartier diamond and pearl tiara that once belonged to Queen Ena, pairing it with diamond floral earrings and the Order of Charles III.
No tiara for Charlene Wittstock at this wedding, as she wasn’t yet a Monegasque princess (not that that has really made a tiara difference, but anyway). But the earrings she chose for the ceremony are beautiful diamond girandoles.
Queen Rania of Jordan wore a tiara to the wedding, but it was her petite Boucheron Bracelet Tiara. She also wore delicate diamond earrings, plus the Order of the Seraphim and the small ribbon of Jordan’s Order of al-Hussein bin Ali.
Rania’s sister-in-law, Princess Rym, wore a delicate diamond tiara. She also wore the Order of the Star of Jordan.
Princess Sarvath of Jordan wore all diamonds — tiara, earrings, brooch, bracelet — with the Order of the Polar Star.
Margarita, wife of the former Tsar of Bulgaria, went sans tiara at the wedding, but she did wear an absolutely stunning necklace. She’s also wearing a Bulgarian order: the Order of Saint Alexander.
Rosario of Bulgaria, here with her husband, Prince Kyril, didn’t wear any jewelry, letting her sparkling gown speak for itself.
Crown Princess Katherine of Serbia wore a small diamond tiara with link-motif earrings and a matching necklace. She’s also wearing a Yugoslavian order, the Order of Saint Sava.
Crown Princess Margarita of Romania (third from the left) wore the family’s Greek Key Tiara, pairing it with diamond earrings, a diamond necklace, and the Romanian Order of Carol I.
