This ballet is a collection of three short works by Balanchine, Emeralds, Rubies and Diamonds. I expect jewels to sparkle, but Emeralds, danced to music by Fauré, didn’t – more like jade than emeralds. Rubies really did sparkle, the costumes and choreography echoing an American parade – all it needed was a few batons to twirl. The music it was set to by Stravinsky was also much more to my taste. The final ballet, Diamonds, fell between the two, more exciting than the first, lacking the pizzazz of Rubies but replacing it with glorious sumptuosity with music by Tchaikovsky. I left having enjoyed it all but not quite sure what was lacking until I remembered Boston Ballet’s interpretations of Balanchine’s choreography earlier in the year (which included another Stravinsky piece). Boston Ballet understand how to swing; Royal Ballet do not. Indeed, I wonder if there is any British ballet company that could have really done justice to this work. All the same, a very enjoyable afternoon, particularly for Rubies.
