    [Product Description]

    The polariscope is one of the most underestimated tools in gemology. Most gemologists use it to quickly determine if the stone at hand is isotropic or anisotropic or, at best, to determine the optic character of gemstones.
    In addition, the polariscope is very useful for distinguishing solid inclusions from negative inclusions as well as for spotting polysynthetic twinning.

    A polariscope uses polarized light for gem identification. It consists of two polarized filters, one on the top and one on the bottom of the instrument. Both the polarizer and the analyzer have their own vibrational planes. When the vibrational plane of the polarizer is at right angles to the vibrational direction of the analyzer, the field between them remains dark. This position is known as the "crossed position". In this position, gems can be tested to determine if they are:

    • isotropic
    • anisotropic
    • anomalously double refractive or an
    • anisotropic aggregate
