The 10 inch diameter dice bowl was a 15th century Ming dynasty piece of porcelain and exceptionally rare.
It was bought by renowned collectors Otto and Gertrude Harriman after World War II when £65 and would have been worth £1,600 in today's money. The family of the late couple decided to sell it at auction with an estimate of £20,000.
But Chinese bidders went into a frenzy over the blue and white bowl and it went for 84 times that amount at £1.68 million.
And according to experts it would have sold for even more had it not been damaged and chipped on the rim.
