Stein attended Lucien Wercollier's sculpture course at the Lycée des arts et métiers from 1947 to 1949.
Stein worked in marble, bronze, stone, and occasionally wood.
Her monumental sculpture commissioned by the Luxembourg state is the 2.50 meter tall travertine sculpture known as La Grande Isis which was put in place in 1980 to the south of the Notre Dame Cathedral.
[5] Stein married sculptor Jean-Pierre Georg (1926–2004) in 1980 and they set up their workshops in the farm they restored in Fennange.
She is remembered in the art gallery in Bettembourg Castle which is named in her honour.
