Karl Lagerfeld has designed a $45,000 collar.

The Chanel designer - who is renowned for his signature high collar - created the neckwear out of metallic leather and included 40 carats of black diamonds with a 22.33 carat emerald as the centerpiece and said the piece is a "show-stopper."

"I'm renowned for my love of a high collar and I wanted to create a true collector's item with this one-off piece. Merging the masculine with the feminine and uniting the world of fine jewelry and high fashion, to me this collar is a work of art and a real show-stopper," he explained.

The piece will be part of an exhibit curated by Vogue jewelry editor Carol Woolton at the Masterpiece London Fair from June 27th-July 4th.
