Traditionally, ‘pigeon’s blood’ is a term used by the local Burmese to describe the fnest hue in a ruby. Some would say it is the colour of a fresh pomegranate seed, others a drop of blood from an artery on a highly polished silver plate. Another

interpretation refers this colour to the center of a live pigeon’s eye, more specifcally, a passenger pigeon’s eye. Burmese gemmologist Han Htun wrote, “A very wise old miner once told me that when you look a white pigeon in the eye you will see a distinct red color. This is “pigeon’s blood,” not the colour of the blood of the animal.” There is, however, a more scientifc way to explain this vivid red found only in the best Mogok rubies. Ruby is composed mainly of aluminium oxide, which is colourless in its purest form. The colour red itself comes from the element chromium that gives ruby its red body colour. What sets a pigeon’s blood ruby apart is the fuorescence efect --- the gem takes in blue and green light and emits red. This red glow helps to mask the darker extinction areas on a ruby and further enhance the redness of the stone, afording it the attractive saturated crimson colour that is comparable to an inextinguishable fame burning from within a ruby.
