Color of Rubies

It is not uncommon to find a wide range of colors in rubies. Colors may range from a pinkish tone to a red with purple and brown hues. The color of ruby varies according to the amount of iron and chromium impurities that are in the stone. Pure red coloring with a slight blue hint is the most sought color of ruby. This color is known as pigeon’s blood. 

Buying the Stone

When buying rubies or jewelry made with rubies, it is important to consider the color first. Clarity is to be considered but not as important as the color. When inspecting the clarity, inclusions are often present. This does not mean the ruby is of lower quality. For example, rutile needles will give a silky shine to the gemstone. When this type of stone is cut in the cabochon style, it produces the cat’s eye effect which is rare. The popular star ruby has inclusions of oriented rutile inclusions. This gives the gem a six rayed star which is a lighting effect known as the asterism.
