The showroom will temporarily close its doors on Sunday 9 January to allow for the project to take place.
The jeweller’s refurbished showroom is set to reopen in spring 2022, and DMR said this will “cement” its commitment to retail in Liverpool.
During the temporary closure, the store’s colleagues will remain on hand remotely and from the company’ other showrooms. Virtual appointments will also remain available during the closure.
DMR’s Liverpool showroom has been open for 12 years. Aside from Liverpool, DMR currently has showrooms in Manchester, Altrincham and Canary Wharf.
DMR said: “We look forward to welcoming you into the new look DMR Liverpool very soon.”
