After originally trading as a stone merchant, Michael Gosschalk opened his first retail premises in 1957 at 20 Motcomb Street in Belgravia, London. Between 1957 and 1965 he was a hugely influential figure in the London jewellery world, his bold designs bringing fun and glamour back into everyday London life, the city still suffering from post-war austerity.

As well as Gosschalk’s own impressive list of private clientele, Andrew Grima sold his jewels exclusively through Gosschalk’s retail outlet before opening his own shop in 1962. After an armed robbery in 1965, Michael Gosschalk closed his London store and relocated to Monaco.
