Ultramarine Blue is a synthetic inorganic blue pigment consisting of a double silicate of aluminum and sodium with sulfide and occurs in nature as a component of the semi-precious stone, lapis lazuli. Processes to make the artificial pigment were devised by Jean Baptiste Guimet (1826) and by Christian Gmelin (1828); but while Guimet kept his process a secret, Gmelin published his and thus became the inventor of "artificial ultramarine."
