The stones represent the human race. The human race is comprised of various ethnicities and beliefs. Stereotypes are awarded to those of a similar skin tone, whether lighter or darker.
Three types of stones are used to give a visual picture of our own condition. These stones are composed in the scene to show how people are interconnected and how our differences do not overshadow what we have in common.
Like these stones, humans can look the same from far away. Yet, if you take the time to look closer, each one is an individual, unique, and special.
