Harry Winston bought the president Vargas diamond in 1938 a year after its discovery in the San Antonio River in Minas Gerais Brazil. It weighed 726.60 carats and named for Getulio Vargas who was then the president of Brazil. Winston cut it into several gems in 1942, the largest retained the formal title of President Vargas, it was a 48.26-carat emerald cut which he sold in 1944 to Mrs. Robert Windfohr. Winston bought it back in 1958 and recut it to a flawless 44.17-carat stone which he sold in 1961 to an undisclosed buyer. It is apparently still in this private collection.
