Margot Robbie wears bracelet made of Emily Brontë’s hair for ‘Wuthering Heights’ UK premiere

Margot Robbie borrowed a one-of-a-kind piece from Charlotte Brontë’s personal collection for Thursday’s “Wuthering Heights” UK premiere in London.

The actress walked the wildflower-lined red carpet wearing a head-turning Dilara Findikoglu corset gown finished with faux blond braids.

But it was the bracelet on her left wrist that instantly caught our eye.

Mourning jewelry dates back as far as the 16th century, but became particularly popular during the Victorian era. Rings, bracelets, pendants and other pieces were crafted in memorial of deceased loved ones, often using locks of their hair.

“Wuthering Heights” author Emily Brönte and her sister Anne died within six months of one another, in December 1948 and May 1949, respectively.

Upon the death of her siblings, Charlotte Brönte commissioned this bracelet fashioned from their hair, braided together and intertwined for all eternity.

The clasp is made of engraved gold, with a large amethyst set in the center and another hanging as a pendant from the base.

Charlotte is said to have worn the bracelet every day, and it now resides at the Brontë Parsonage Museum.

Robbie’s hair-raising gown was, perhaps, only outshone by the remarkable piece of history on her wrist.

Her dress was constructed from sheer silk chiffon, fitted with a boned corset bodice and crisscrossed with golden braids from top to toe.

Around her neck was a braided choker that echoed the look of the Brontë bracelet, and Robbie and stylist Andrew Mukamal turned to Jessica McCormack for some additional sparkle, choosing garnet, diamond and pearl earrings along with a 4-carat ruby ring.

A duo of archival Boucheron brooches set with glimmering red stones — one from 1900, the other from 1920 — finished Robbie’s regal look.

While Robbie’s “Wuthering Heights” press tour outfits have all been spectacular so far, she and Mukamal have truly outdone themselves by incorporating the book’s author into their latest look.
