Notes: The brothers Walter and Harold Child began making jewellery in 1880 in London. They started making neo-renaissance pieces, but became well known for their Art Nouveau designs and enamel work, especially their range of colour. They worked together for the next twenty years until Walter Child left the business. Harold Child continued to trade at Alfred Place West (now Thurloe Street in South Kensington) until 1915. In the years before the firm closed they could list Queen Victoria, George V and Edward VII, amongst other Royalty as their clients.
