The Danish royal family doesn’t just include Queen Margrethe II and her descendants. The extended family also encompasses the former royal family of Greece, as well as the German House of Sayn-Wittgenstein-Berleburg. Today’s sparkler, the Sayn-Wittgenstein-Berleburg Diamond Spike Tiara, is worn by a member of Princess Benedikte’s family.

The tiara features a series of diamond spikes topped with round brilliants. The spikes are interspersed with smaller round brilliants and set atop a base of diamond scrolls with suspended diamonds.

The tiara has so far only been worn by one member of the family: Carina Axelsson, the partner of Prince Gustav of Sayn-Wittgenstein-Berleburg. She debuted the tiara about a decade ago, wearing it for two events during the 70th birthday celebrations for Queen Margrethe II in Copenhagen in April 2010.

A few months later, Carina wore the tiara again, this time for the wedding of Crown Princess Victoria and Prince Daniel of Sweden in Stockholm.

In 2012, Carina also made a pair of appearances in the tiara. In January, Queen Margrethe celebrated her Ruby Jubilee, and Carina wore the tiara for the theater gala during the celebrations in Copenhagen.
