In August 1703, de Lamerie became the apprentice to a London goldsmith of Huguenot origin, Pierre Platel (1659–1739). De Lamerie opened his own workshop in 1713 and was appointed goldsmith to George I in 1716. He worked in partnership with Ellis Gamble - formerly apprentice to Master William Hogarth - between 1723 and 1728. His early work is in the simple Queen Anne-styles, following classical French models, but de Lamerie is noted for his elaborate Rococo style of the 1730s, particularly the richly decorated works of an unidentified craftsman, the Maynard Master.
