1.02ct Pair of Heart Shape Rubies 4.5x4.5mm

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): 4.5x4.5;Carat Weight (ct): 1.02
