George Balanchine choreographed it back in 1967 for the New York City Ballet. One of the first abstract ballets. The parts, which many consider separate ballets, are named for the costumes. Rubies dancers wear vivid red, Emeralds they wear long green skirts and jeweled tops, and in Diamonds they are the flat Russian style tutus that are bejeweled.
Of course not. I will leave them at will call under your name. Is that alright?
