1.02ct Cushion Cut Ruby 6.4x6mm Bergeon 4668 Ceramic Heating Crucible Various test positionsRubys hues vary from orangey red to purplish red and the presence of chromium is the trace element that causes the unparalleled ruby red colour. 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. ;
