I think that the gems were organized into familes based on gem type. (Ex- Quartz) And the four heads of the families are/were the great diamond authority. The four diamonds symbolize those families. This is supported by the fact that in peridot's ship there are 3 triangles, the same as the four diamonds, possibly symbolizing how Rose Quartz rebelled against the other authority figures and was kicked from the group.
