In 2005, a British jeweller made the world’s most expensive tea bag to celebrate the 75th birthday of PG Tips.

The bag was studded with 280 diamonds and worth £7,500.

Pete Harbour, spokesman for PG Tips said: “As it’s our 75th birthday, we wanted to do something special to remind people just how much they love the great British cup of tea.”

The tea bag was donated to a charity auction for Manchester Childrens’ Hospital in England.
