She became known internationally as one of the Baby Ballerinas of the Ballet Russe de Monte Carlo, after being discovered by her fellow émigré, balletmaster and choreographer George Balanchine. She was featured in numerous ballets in Europe. Balanchine also featured her in his productions at Ballet Theatre, New York, making her the star of his performances in the United States. While most of Toumanova's career was dedicated to ballet, she appeared as a ballet dancer in several films, beginning in 1944.
After moving to Paris, Toumanova was given piano lessons and studied ballet with Olga Preobrajenska, who she described as her "first and only permanent teacher" and an "immortal friend". At the age of six, the ballerina Anna Pavlova invited young Toumanova to perform in one of her gala concerts (08.06.1925). Toumanova danced a polka choreographed by Preobrajenska. The girl was ten when she made her debut at the Paris Opera as a child étoile in the ballet L'Éventail de Jeanne (for which ten French composers wrote the music). Toumanova's dancing astounded critics.
Toumanova quickly became recognised as a young prodigy of immense talent. She came to be called "The Black Pearl of the Russian Ballet", because, as A.V. Coton[who?] wrote, "she was the loveliest creature in the history of the ballet", with black silky hair, deep brown eyes and pale almond skin. Toumanova was considered the most glamorous of the trio. Throughout her dynamic career, her mother was her devoted companion, nursemaid, dresser, agent and manager – she was always at the helm.
Balanchine created the role of the "Young Girl" for Toumanova in his ballet Cotillon and had her star in his Concurrence and Le Bourgeois Gentilhomme. Léonide Massine also worked closely with Toumanova in the creation of many of his ballets. She played the part of the Top in his Jeux d'Enfants. Balanchine created a role for her in his Le Palais de Cristal (since re-titled Symphony in C) in 1947 at the Paris Opera.
In 1936, while Toumanova was performing ballet in Chicago, a 16-year-old boy named Burr Tillstrom came to see her perform. Following the ballet, Burr went backstage to meet her. As they talked, Toumanova and Tillstrom became friends. Some time later, Tillstrom showed her a favorite puppet he had made and she, surprised by his revelation, exclaimed, "Kukla" (Russian for "puppet"). Burr Tillstrom went on to create a very early (1947) television show for children, titled, Kukla, Fran and Ollie.

In 1944 Toumanovna married Casey Robinson, whom she met as the producer and screenwriter of Days of Glory, her first film. They divorced on October 13, 1955, due to his infidelities.
Toumanova died in Santa Monica, California, on May 29, 1996, aged 77, from undisclosed causes. Before her death, she gave her Preobrajenska costumes to the Vaganova Choreographic Museum in St Petersburg, Russia. She was buried next to her mother Eugenia in Hollywood. In his obituary, British choreographer John Gregory was said to describe Toumanova as a "remarkable artist – a great personality who never stopped acting. It is impossible to think of Russian ballet without her."
