A diamond-studded locket swallowed by a New Zealand man who tried to steal it has been "recovered", police say. The Fabergé egg locket, valued at NZ$33,585 ($19,300; £14,600), was recovered in a "natural" manner. "Medical intervention [was] not required," they told the BBC.

The Winter Egg’s record stood until 2007, when the Rothschild Egg, a dazzling 1902 specimen featuring a clock and an automaton, sold for $18.5 million at another Christie’s auction. Now, the Winter Egg has claimed the record once again.
