A Singapore court has sentenced an Indian tourist to more than two years in prison for attempting to steal a $154,000 diamond from a Chinatown jewellery store by substituting it with a counterfeit. Mangroliya Manojkumar Kurjibhai, 41, distracted store staff while his accomplice, Serasiya Milan Ramnikbhai, 30, swapped the 4.95-carat gem with a fake that had been concealed in his mouth — a counterfeit reportedly crafted in India to match the real stone's specifications and serial number. Surveillance footage exposed the scheme, and both men were arrested at Singapore's airport the same day, with the stolen diamond recovered from their luggage; Serasiya remains in remand ahead of a hearing on Friday.
