Pleochroism is the collective term for any such phenomena. If two main colors
can be observed, it is often called dichroism; three colors, trichroism. Dichroism is
possible only in tetragonal, hexagonal, and trigonal crystal systems; trichroism ...
With the diamond cut, the ideal total reflection and the highest brilliance has been
reached. Pleochroism Some gems appear to have different colors or depth of
color when viewed in different directions. This is caused by the differing
absorption ...
The effect is called pleochroism ('many coloured'), and when the light passing
through the stone is split into two colours or shades the stone is said to be
dichroic; if three colours or shades are produced, the gem is trichroic. Dichroism
is ...

Mineralogical Applications of Crystal Field Theory
Pleochroism, or dichroism when it occurs in uniaxial crystals, may be observed in
minerals belonging to all crystal systems except the cubic system. This fact
provides one clue to the cause of pleochroism, that it originates within cations in ...

Where both a and y have been determined, the birefringence can be shown to
increase dramatically with increasing Fe'+ (from -0.030 to >0. l00). but because of
the intensity of pleochroism this is difficult to observe. Most stilpnomelanes show

PLEOCHROISM If white light is transmitted through any substance it will be found
that somewhat less light emerges than entered. In other words, it will be found
that the substance absorbed part of the light. If the amount of light absorbed is ...
