The Star of South Africa, Silver, post-nominal letters SSAS, was instituted by the State President on 1 July 1975, as the junior decoration of two military classes of the Order of the Star of South Africa. The order was named after the first large diamond to be found in South Africa, the Star of South Africa, which was found on the banks of the Orange River in 1869 and which sparked the New Rush, leading to the establishment of Kimberley. The Order of the Star of South Africa was expanded on 17 October 1978, when a non-military division, with decorations in five classes, was instituted for conferment on civilians and, from 1988, on senior police, prisons service and intelligence service officers, as well as foreign military attachés. The second of these five non-military decorations, the Star of South Africa, Grand Officer, ranks on par with the Star of South Africa, Silver.
