How are NFTs affecting high jewellery investments? Metaverse marketplace OpenSea sells diamonds while Sotheby’s auctioned earrings inspired by a Van Gogh artwork – with accompanying digital token

• Digital Twin’s NFT auction offered a pair of 18k gold earrings designed by Payal Shah of L’Dezen, whose creations have been seen on Rihanna and Michelle Obama
• Investment-grade diamonds can be found on metaverse marketplaces like OpenSea – buyers get an NFT that represents ownership of a physical asset secured in a vault
