The vase in use.
A vase that was used to keep flowers in by its unwitting owners has sold for £3 million after it was revealed to be a rare 18th century Chinese relic.
The 16-inch yellow and green ceramic was sat on top of a chest of drawers in its owners' house when eagle-eyed auctioneers spotted its significance.
But even the experts at Christie's in London underestimated its true worth after it sold for 15 times the £200,000 price they tipped it to fetch.
Unbeknownst to its owners the vase was actually a remarkable 300-year-old artefact from the Imperial kilns of the Yongzheng emperor.
