This is a jewellery business, not a musician or music supplier. Durrants of London Ltd, based in Hatton Garden, is a family-run jeweller specialising in bespoke diamond and gemstone pieces. The evidence provided describes their 50-year history in fine jewellery design, craftsmanship, and diamond sourcing. They do not offer music services, DJing, entertainment, or any event music supply. The source material covers jewellery consultation, design, and handcrafting only. This listing cannot be completed as submitted because the business lane (MUSIC supplier) does not match the actual trade (jewellery retail and bespoke design). No valid event music supplier information is available.
