Ruby’s 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 “pigeon’s 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.;Stone Size (mm): 8.5x7.4x4.4;Carat Weight (ct): 3.16
