General
and Scientific Details of the Ruby gemstone

A ruby is a pink to blood-red colored gemstone, a variety of
the mineral corundum (aluminium oxide). The red color is caused mainly by the
presence of the element chromium. Its name comes from ruber, Latin for red.
Other varieties of gem-quality corundum are called sapphires. The ruby is
considered one of the four precious stones, together with the sapphire, the
emerald, and the diamond.
Prices of rubies are primarily determined by color. The
brightest and most valuable "red" called pigeon blood-red, commands a
large premium over other rubies of similar quality. After color follows
clarity: similar to diamonds, a clear stone will command a premium, but a ruby
without any needle-like rutile inclusions may indicate that the stone has been
treated. Cut and carat (weight) are also an important factor in determining the
price.
Rubies have a hardness of 9.0 on the Mohs scale of mineral
hardness. Among the natural gems only moissanite and diamond are harder, with diamond
having a Mohs hardness of 10.0 and moissonite falling somewhere in between
corundum (ruby) and diamond in hardness. Ruby is α-alumina (the most stable
form of Al2O3) in which a small fraction of the aluminium3+ ions are replaced
by chromium3+ ions. Each Cr3+ is surrounded octahedrally by six O2- ions. This
crystallographic arrangement strongly affects each Cr3+, resulting in light
absorption in the yellow-green region of the spectrum and thus in the red color
of the gem. When yellow-green light is absorbed by Cr3+, it is re-emitted as
red luminescence. This red emission adds to the red color perceived by the
subtraction of green and violet light from white light, and adds luster to the
gem's appearance. When the optical arrangement is such that the emission is
stimulated by 694-nanometer photons reflecting back and forth between two
mirrors, the emission grows strongly in intensity. This effect was used by
Theodore Maiman in 1960 to make the first successful laser, based on ruby.
All natural rubies have imperfections in them, including
color impurities and inclusions of rutile needles known as "silk".
Gemologists use these needle inclusions found in natural rubies to distinguish
them from synthetics, simulants, or substitutes. Usually the rough stone is
heated before cutting. Almost all rubies today are treated in some form, with
heat treatment being the most common practice. However, rubies that are
completely untreated but still of excellent quality command a large premium.
Some rubies show a three-point or six-point asterism or
"star". These rubies are cut into cabochons to display the effect
properly. Asterisms are best visible with a single-light source, and move
across the stone as the light moves or the stone is rotated. Such effects occur
when light is reflected off the "silk" (the structurally oriented
rutile needle inclusions) in a certain way. This is one example where
inclusions increase the value of a gemstone. Furthermore, rubies can show color
changes—though this occurs very rarely—as well as chatoyancy or the "cat's
eye" effect
Generally, gemstone-quality corundum in all shades of red,
including pink, are called rubies.However, in the United States, a minimum
color saturation must be met to be called a ruby, otherwise the stone will be
called a pink sapphire. This distinction between rubies and pink sapphires is
relatively new, having arisen sometime in the 20th century. If a distinction is
made, the line separating a ruby from a pink sapphire is not clear and highly
debated.As a result of the difficulty and subjectiveness of such distinctions,
trade organizations such as the International Colored Gemstone Association
(ICGA) have adopted the broader definition for ruby which encompasses its
lighter shades, including pink
