Diamond worked as a journalist. In 1884, he launched The Irish Tribune and in 1887 acquired the Glasgow Observer as well as The Catholic News, which he both amalgamated into The Catholic Herald, of which he was editor in charge until his death, aged 75, in 1934. In 1888 he founded the Weekly Herald, Catholic Educator and Manchester Citizen newspapers. In 1899, he bought the Aberdeen Catholic Herald. Throughout his life he established 37 weekly newspapers.
Diamond was an outspoken and controversial figure, described by one of his successors as "the kind of a man who made a good many enemies". On 8 January 1920 he was arrested and charged with publication of an article in the Catholic Herald that allegedly encouraged assassination in Ireland.
Diamond entered the British House of Commons as an Anti-Parnellite Nationalist in 1892, sitting for North Monaghan the following three years. He contested Peckham in the 1918 general election and Rotherhithe in the 1922 general election, as a Labour Party candidate, however was unsuccessful. Extensive travels led him through Southern Africa, America and Southern Europe.
