British designers Elizabeth & David Emanuel created Diana's famous gown

This is going to be some expensive champagne! A bottle of 1961 vintage Dom Perignon champagne that was used at Britain’s Prince Charles and Princess Diana’s wedding will be auctioned off soon.

The 1961 vintage Dom Perignon had been selected for the wedding because it was the year Diana was born.

James Grinter of auction house Reeman Dansie said, “It is very rare to find a Royal Wedding bottle of 1961 Dom Perignon because it was a strictly limited release and even rarer to find it still sealed in its original box.”

Evidently only 99 bottles of the vintage – regarded as one of the finest ever produced – were shipped across from the France’s Champagne region for the wedding.

All the bottles are believed to have been consumed at the Buckingham Palace reception, but a similar boxed and sealed bottle was sold in 2004.

As much as I love champagne, this would be one bottle I could never open.
