American rapper, record producer, and the Grammy Award-winning artist Pharrell Williams attended Nigo’s Kenzo show in Paris wearing a pair of custom-designed Tiffany & Co. sunglasses in 18k gold with 61 round brilliant diamonds of over 25 total carats and two emerald-cut emeralds.

“Tiffany and I are engaged,” the rapper confirmed to the press, showing off the sunnies at the photocall and on the front row. The custom-designed sunglasses are the first in a line of items that Williams has planned to do with the American jeweler, though he was shy to reveal more details. The sunglasses are an instant collector’s item that will surely sell out—should it hit the market.

Pharrell is no stranger to jewellery design, having worked with Louis Vuitton in 2008 on a jewellery line. He is also one of the faces of Chanel and has worked with various other fashion brands like Moncler, Moynat, Adidas and G-Star. Unsurprisingly, his collabs often include sunglasses (much like his 2005 Louis Vuitton Millionaire collection, designed together with Nigo, which has now achieved grail status).
