Former investment banker Connie Nam founded this jewellery brand from her Notting Hill flat in 2012. The Seoul-born entrepreneur spent £500 on a website to launch Astrid & Miyu, named after Swedish and Japanese words for ‘beautiful’. Astrid & Miyu has 17 stores in the UK and opened their first US store in New York in June last year. The brand’s celebrity fans include Georgia May Jagger, Pippa Middleton and Rochelle Humes.
