Auctioneer Robert Stones brought down the gavel at £350,000 (£420,000 including the 20% buyer's premium) after almost nine minutes of bidding.
Four phone bidders from Mainland China and London competed against a lady sitting in the saleroom who had flown from China to attend in person. She left empty-handed when it sold to a bidder on the telephone.
The jar was offered at the sale on November 27 by the Shropshire descendant of a Liverpool shipping merchant who had brought it back from China. Admired for its 18in (46cm) body decorated in doucai enamels outlined in gilt with foliate lotus scrolls and iron red bats in flight - respectively symbols of enlightenment and good fortune - no other closely related vase appears to have been published.
In 2011 it had failed to sell at Sotheby's in London but was offered in Cheshire with a substantially lower estimate of £150,000-200,000.
The price was the highest realised for an Asian work of art among a raft of regional specialist sales.
