A diamond-winged tiara created by Cartier will go on display when the V&A Dundee opens next year.

The ornamental crown, created in 1935, is the last of its type made by the French company and was Inspired by the winged helmets worn by the heroines of Wagner's opera cycle Der Ring des Nibelungen.

The tiara will go on display in the V&A Dundee Scottish design galleries when the new museum opens in the second half of 2018 and will be the first time it has gone on public display.

The piece, known as a Valkyrie tiara, comprises more than 2500 cushion-shaped, single-cut, circular-cut and rose-cut diamonds, set in a gold and silver frame.

The wings were constructed using wire-coiled springs so they move slightly when worn. The wings can also be detached and worn separately.

The headpiece was commissioned by Mary Crewe-Milnes, Duchess of Roxburghe, in the year of her marriage to the 9th Duke of Roxburghe, George Innes-Ker, when the couple resided in Floors Castle near Kelso.

Joanna Norman, lead curator of the Scottish design galleries, said: "This tiara is a stunning example of design being directly influenced by the person who commissioned it.

"In 1935, the Duchess of Roxburghe had just married into a Scottish dynasty. When she asked Cartier to make one last Valkyrie tiara she was commissioning a piece of exquisite craftsmanship and unexpected design, inspired by the fashions of her childhood.

"The tiara is an amazing piece which trembles when worn to give a sense of moving feathers. The designed allowed the duchess to remove the wings and wear them as brooches if she so desired."

The duchess' tiara will be displayed in a section of the Scottish design galleries focused on design as a form of storytelling, highlighting how it can be used to spark the imagination and make the world more beautiful.
