Seafood fan David Broomfield recently discovered his second precious stone while he was tucking into an oyster at Manning's Seafood stall in Margate.
The 73-year-old from Broomfield, Herne, heads to the seaside town on a weekly basis to pick up whelks and, when they're available, oysters.
And it's not the first time that he's stumbled across one – back in 1997, the lucky man found a smaller one when he was enjoying a meal in Falmouth.
But despite his success, he reckons that he won't be able to form a piece of jewellery from the pretty pieces anytime soon.
The oyster fan was quoted in the Canterbury Times explaining: "At this rate it's going to take me some time to make up a necklace. I might make a pair of earrings if I'm lucky, but at 73, I don't really think it's likely!"
