John Brereton Jewellers was established in 1916 at 108 Capel Street, Dublin. Specialising in both new and antique jewellery the business has grown with the city of Dublin. By the early 1970's with the third generation of Breretons, Jack's sons John and Liam, joined the company and opened the company's second store on Chatham Street, Dublin. The third store, opposite the General Post Office (GPO) on Dublin's O'Connell Street, opened in 1986.
In 2003 Paul Brereton, part of the fourth generation to join the family business, graduated as a gemologist from the Gemological Institute of America in 2006. Paul now works closely with his father and uncle in the running of the three unique stores. Together they share over 100 years of jewellery experience. This enables John Brereton Jewellers to offer their customers some of the finest diamonds and jewellery in Ireland today.
