The family's best set of emeralds can trace its roots back to the first Bernadotte king, Carl XIV Johan (1763-1844). It started out, believe it or not, as a belt - a very fancy belt for a very fancy military uniform. The emeralds are mentioned in the first inventory of the Bernadotte Family Foundation completed in 1844. Today, most of the belt is used as a necklace made of plaques of different shaped emeralds surrounded by delicate diamond designs. To go with the necklace, the set includes two brooches, one large (the former belt buckle) and one small.
With just the necklace and brooches in the set, the emeralds are usually paired with diamond earrings and a diamond tiara (Princess Sofia's Emerald and Diamond Tiara is the only emerald tiara in the family at this time). Carl Gustaf's mother, Princess Sibylla, was fond of wearing them with the Connaught Tiara; pictured above, Princess Lilian (far right) paired them with the Baden Fringe Tiara at the Nobel Prize ceremony in 1976.
At Nobel time, Crown Princess Victoria has been slowly debuting new-to-her pieces from the jewels usually reserved for Queen Silvia for the past few years. In 2012, she wore the emeralds for the first time with the Four Button Tiara (and a green sequined Elie Saab gown, for the complete Kermit effect). She also got creative with the large brooch by attaching it to the back of her elaborate updo.
