Together they launched the Webb Ellis Cup on its 100-day journey around the UK and Ireland, during which it will make more than 300 stops.
The event, on Wednesday (June 10), also marked the start of the Festival of Rugby, which will see celebrations taking place far and wide between now and the tournament final on October 31.
The prince, who is honorary president of England Rugby 2015, said: "This tournament – the most significant moment in English rugby since that night in Sydney in 2003 – has the ability to broaden the reach of the game and deliver a long lasting legacy for the sport.
"With 48 matches spread across the country, I hope every community can be part of this tournament and celebrate the game of rugby."
Rugby fans will be able to see the trophy at two public events in Isleworth during its tour:
- Wednesday, August 12, 7pm-9pm, at Tesco, Mogden Lane, Isleworth TW7 7JY - pose for a photo with the Webb Ellis Cup and enter a competition to win VIP tickets to a Rugby World Cup match at this event, organised by Heineken.
- Sunday, September 13, 10am-3pm, at Redlees Park, Worton Road, Isleworth TW7 6DW - Try your hands at rugby and a host of other sports at this fun day, organised by Hounslow Council. There will also be a free musical festival and food and drink from around the world.
Tournament chiefs announced this week that more than 2m tickets had already been sold and 6,000 volunteers had been recruited to welcome visitors and help the competition run smoothly.
They also confirmed they were making 15,000 free tickets available for community groups and young people and rugby development programmes.
Two Rugby World Cup warm-up events will take place this August and September at Twickenham Stadium, which will host 10 matches during the tournament.
