The most valuable colour is the pigeons blood variety which is a vibrant red without any orange or purple tint. Some rubies display the gemmological phenomenon called asterism where cabochon cut stones have a whitish star on top of the dome. This is created by fine intersecting rutile needle inclusions. ;
