The redesigned store features contemporary fittings, spotlighting and clean white surfaces to create a fresh, premium feel.
The shop front window is outlined by sharp, jagged edges to translate the key brand message of "From rock to ring".
The store design is the collaborative work of Walford Wilkie and Blauel Architects.
Julian Walford, founding managing director at Walford Wilkie, said: "We conceptualised the store to project the essence of Holts business -- taking rough-hewn stone and turning it into exquisitely beautiful jewellery."
Holts appointed Walford Wilkie for brand strategy development back in 2005 and the agency continues to work on Holts' brand development.
The diamond expert runs many services including jewellery design, gem matching, appraisal, gemstone testing, cutting, polishing and bead stringing.
