It was a night of celebration and emotion as Harry Potter and the Deathly Hallows Part 2 afterparty kicked off at Old Billingsgate Market in London, but despite shedding a few tears at the premiere, Emma Watson held her head high as the night continued.
The actress, who plays Hermione Granger, appeared to have a glittering theme for the night and changed outfits for the afterparty.
And she sparkled like a diamond in both of her stunning couture dresses with a real rock to match, wearing a Boodles round diamond ‘Chakra’ platinum ring worth a cool £95,000.

She then changed into a third and final outfit for the night, consisting of a little black dress, to head back to her hotel.
Also letting their hair down at the afterparty were her fellow co-stars Rupert Grint, Tom Felton and engaged couple Bonnie Wright and Jamie Campbell Bower.
But Harry Potter's star Daniel Radcliffe was a no-show at the event, which saw Chloe Green and Sam Branson turn up for a celebratory drink.
Perhaps his lack of party spirit was due to the fact that the actor has given up alcohol, after recently admitting that the pressures on fame had made him dependent on drinking.

Speaking with his co-stars, Harry Potter star Daniel said: ‘I don’t think the end of the story happens tonight because each and every person who will see this film will carry this story with them through the rest of their lives.
‘A huge thank-you to all of you, first of all for giving me a job and Jo for letting him give me a job.
‘Every opportunity I get from now on all goes down to the fact I got very, very lucky when I was eleven.’

While author J.K. Rowling told Daniel and fans that it’s not the end, seeing as the series will always live on in their hearts.
And Grint, who plays Ron Weasley, took the opportunity to thank the author for what she had done ‘for ginger people’ in front of the screaming crowds.
Emma said: ‘It’s overwhelming to try to find the words to say what I want to say, but I have been so privileged to play this role and be a part of these films.
‘I’ve had the most amazing 10 years of my life. Thank you so much.’
