Affordable luxury jewellery, trading under the name Diem, has been in the business of selling high end jewellery of the finest quality to clients from UK and abroad for the past 25 years from our premises in Mayfair, London. We passionately believe that quality does not necessarily have to be beyond reach or for the very few. Our collection includes pre-owned pieces by world renowned jewellers including Cartier, Tiffany, Bulgari, Van Cleef and Arpels amongst many others. We exhibit at all major fairs in the UK and welcome any inquiries in person or via email.
