The dinner was held at the Buckingham Palace and Dongre, whose creation was picked by Middleton during her India visit last year, posted a picture from the evening on her Instagram account.
For the gala the Duchess of Cambridge wore a jewellery piece from Dongre's Pinkcity line.
"Was so lovely meeting The Duchess of Cambridge this evening. We chatted about our mutual love for Rajasthan and she chose to wear a pair of @anitadongrepinkcity earrings crafted by @jet_gems," the designer tweeted.
