Diana's feng shui letter fetches £640

A letter hinting at Princess Diana's belief in feng shui to help heal after her split with the Prince of Wales sold for £640 at auction on Wednesday.

The letter was written by the princess in June 1994, the same month that Prince Charles confessed to his affair with Camilla Parker Bowles in a television interview with Jonathan Dimbleby.

The letter was snapped up by an anonymous bidder at the Dominic Winter auction in Cirencester, Gloucestershire.

In her letter, Princess Diana said that a feng shui expert visited her Kensington Palace home and she rearranged her bedroom and sitting room on his advice. Feng shui is the ancient Chinese system of arranging furniture and positioning objects to encourage the flow of positive energy and fend off negativity.

She wrote: "I had a fascinating time with him as he travelled around my 'stressed out' environment." Also up for auction were a 1993 Christmas card sent from Princess Diana featuring a photograph of the Princess with Princes William and Harry, which fetched £640, and a 1996 signed photograph of Princess Diana with charity fundraisers, which was bought for £760.

Two bidders each snapped up a catalogue from a charity auction of some of Princess Diana's dresses by Christie's New York, which fetched £250 and £260 respectively.

The five lots fetched £2,550 in total.
