A piece of jewellery worn by the late Princess Diana on one of her final public engagements is to be sold.
The diamond and South Sea pearl necklace (pictured) was purchased two years after the Princess' death by a US collector who paid more than £360,000 to buy it with a pair of matching earrings
Now, the Texan millionaire is putting the jewels - known as the Swan Lake suite because Diana was wearing the necklace at a performance of the ballet in 1997 - up for sale.
For the last 11 years, the items have remained in a locked cabinet at Mr McIngvale's Houston store.
The estimated price of the set is around £500,000.
