Jules Porges (1839-1921), one of the first diamond dealers to have mines in Kimberly before selling his shares to De Beers. He gave this jewel afterwards to his daughter Elly Porgés (1878-1946) who became Marquise de la Ferté Meung after her marriage the Marquis in 1898. Jules Porges (1839-1921), descended from a prominent Austro-Hungarian family, was born in Vienna and was raised in Prague where his father was a master jeweler. By the 1860s he had settled in Paris where he quickly established himself as a leading force in the diamond trade and founded Jules Porges & Company. By the time diamonds were discovered in South Africa, he had amassed a tremendous fortune and was considered the leading diamond merchant in the world. In 1876, Porges himself arrived in Kimberley, playing the unusual role as both consumer and producer of diamonds.
