This Dichroscope shows whether a stone
is dichroic (reflects 2 colors) or not. This can be helpful
in differentiating stones of the same color from one another.
The light entering the dichroscope is broken into two polarized
rays that have vibrational directions at right angles to
each other. The two images in the dichroscope represent
the polarized light and the pleochroic colors signifies
doubly refractive stones except if the stone is viewed thru
the optic axis. Single color in the dichroscope represents
singly refractive stones. If no dichroism is identified
in the first assessment, the stone can be turned and viewed
in other directions. Trichroic gems can also be distinguish
and will reveal three colors if the stone is viewed in three
directions perpendicular to each other. This tool is useful
in identifying gemstones that are still in the rough, in
set and difficult to view with other instruments.
