Not just the driving force behind the Chanel label, Karl Lagerfeld is also regularly cited as a fashion icon in his own right, lauded for his strict fashion uniform of monochromatic colours and a high-collared shirt.

Now Karl has taken his high-collar obsession and turned it into a special one-off piece which went on sale exclusively at Net-a-porter.com today. “I’m renowned for my love of a high collar,” said Lagerfeld. “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 jewellery and high fashion, to me this collar is a work of art and a real show-stopper.”

Certainly a show-stopper in comparison to your average shirt collar, Lagerfeld’s metallic leather collar is set with over a thousand 40-carat black diamonds and features a stunning 22.33-carat emerald at the neck. As you can imagine, being the only one in the world, Karl’s collar is not cheap - the exclusive design costs £29,000, with a percentage of profits from the sale being donated to the children’s cancer charity CLIC Sargent.

For those lacking in a lottery win, the collar will also be on display at Masterpiece London as part of jewellery writer Carol Woolton's Brilliant exhibition from June 28 until July 4.
