Great Diamond
The Great Diamond is an asterism. Astronomy popularizer Hans A. Rey called it the Virgin's Diamond. It is composed of the following stars: The Great Diamond is somewhat larger than the Big Dipper. The three southernmost stars are sometimes regarded as being their own asterism, the Spring Triangle. Lying within the Great Diamond is the set of stars traditionally assigned to Coma Berenices. Many nearby galaxies, including galaxies in the Virgo Cluster, are within this asterism, and some of these galaxies can easily be observed with amateur telescopes.
