This was designed in celebration of UK tea company PG Tips' 75th birthday in 2005. As a promotion, they had a contest, and participants could win the diamond-studded tea bag estimated at about £7,500 (roughly $12,000).
According to spokesman Pete Harbour "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."
Runners-up received a limited edition teapot and a year's supply. No word yet on how the diamond-studded tea tasted.
