While the Queen may own a vast collection of diamond tiaras, her European counterparts can certainly give her a run for her money.

To celebrate Queen Margrethe II of Denmark's 40 years on the throne, the Royals of Europe gathered in Copenhagen for a gala dinner – and to show of some very important jewels.

Of the younger Royals, Princess Mary of Denmark, not surprisingly, wore the most sparkling tiara and necklace set,including diamonds and rubies.

Mass celebrations over the weekend saw thousands of Danes line the streets, waving flags and cheering as the
queen passed by in a horse-drawn
golden carriage.

Known as Daisy, the queen is popular, with a
poll last month showing that nearly eight out of 10 Danes are in favour
of their monarch.

Margrethe has seen her popularity soar since the beginning of the 1980s as she began establishing herself as a talented artist.
