Henry Mullins started working at 230 Regent Street in London in the 1840s and moved to Jersey in July 1848, setting up a studio known as the Royal Saloon, at 7 Royal Square. Here he would photograph Jersey political elite (The Bailiff, Lt Governor, Jurats, Deputies etc), mercantile families (Robin, Janvrin, Hemery, Nicolle ect.) military officers and professional classes (advocates, bankers, clergy, doctors etc).

His portrait were printed on a carte de visite as a small albumen print, (the first commercial photographic print produced using egg whites to bind the photographic chemicals to the paper) which was a thin paper photograph mounted on a thicker paper card. The size of a carte de visite is 54.0 × 89 mm normally mounted on a card sized 64 × 100 mm. 

This diamond cameo was inspired by Henry Mullins who created diamond cameos of Jersey citizens in 1848.
