The dress, which was custom made for the actress and features a whopping 6,000 pearls, was stolen from a room at the London Hotel in Hollywood earlier this week. Calvin Klein, who created the magnificent bespoke creation for the Academy Award-winning actress, have yet to comment on the theft.

Calvin Klein creative director Francisco Costa designed the red carpet stunner for Nyong'o, who wowed at the 2015 Oscars ceremony wearing the open-back masterpiece. Following the theft, the police have put the value of the gown at $150,000; however AmericanPearl.com, an e-commerce luxury jewellery retailer, has calculated the value at about $1 million wholesale, or $10 million at auction according to WWD.

“Based on our analysis of the size range of the pearls used in the dress, over a hundred 16-inch strands of natural pearls of 4 millimeters to 7 millimeters in diameter would be needed to create this dress. Natural pearl strands of this size and quality are easily valued at $10,000 each for fair market value,” said Heidi Cohen, director of marketing for American Pearl. Adding that Costa created the gown out of natural pearls.

“The $150,000 estimate that many news outlets are reporting would be an approximate estimate for cultured pearls. Knowing how rare natural pearls of this quality are, we estimate the value of the dress much higher for just the raw pearls alone, which may be why the dress became a target for theft.”

According to reports, the one-off gown was stolen some time during the day on Tuesday when Nyong'o was out of her room. West Hollywood sheriff’s detectives said they were investigating the theft.
