Ernest Jones is a British jeweller and watchmaker. Established in 1949, its first store was opened in Oxford Street, London. Ernest Jones specialises in diamonds and watches, stocking brands such as Gucci and Emporio Armani. Ernest Jones is part of the Signet Jewelers group.
Ernest Jones is from England.
This is difficult because most people think of British as English but British is also Welsh, Scottish and Northern Irish so he could've been any of them and not necessarily from England.
