Rubies - gemstones in glowing red

The name "ruby" is given to all red gemstones from the corundum group. The name of these coveted gems is derived from the Latin word for red, rubens, and is also used to describe an intensive, glowing shade of deep red such as that of the gems.
However, rubies also exist in a range of further hues which may have orange or pinkish undertones. The most valuable is known as pigeon's blood red and has a subtle blue shimmer.
Pleochroism is an optical phenomenon seen in rubies in which the stone changes colour when viewed from different angles. The range of colours characteristic of rubies ranges from yellowish red to deep red.

The significance of clarity and cut in rubies

Coloured gemstones are classified into three categories of clarity. Rubies are Type II stones which generally contain inclusions. As with many gemstones, the most precious rubies are those with the highest clarity and transparency. However, impurities need not indicate lower quality; when found in rubies, they may create an enchanting one-of-a-kind stone provided they are not excessively large or obvious and do not impair the durability of the stone.
A faceted cut of perfect symmetry, executed with care, is the best way to enhance the beauty of a ruby.

Rubies - a stunning play of light and colour

Rubies contain inclusions of rutile needles that may create special visual effects. Some stones have a cat's eye effect (chatoyance) in which a narrow luminous band plays across the surface of the stone when it is moved.
In rare cases, rubies display a six-pointed star effect created by the intersection of three linear inclusions - a phenomenon known as asterism.
Aventurescence, or schiller effect (an optical reflectance effect) may also add a silk-like shimmer to the stone.
