Universal gemoscopic stage, characterized in that it is constituted by a set of two concentric rings, in which the outer ring swings in an oscillating support mounted on an optical analyzer apparatus, while the inner ring is rotatable with respect to the first and has a supporting device for a longitudinally displaceable orthoscopic immersion cuvette, whose cuvette contains a device for fastening a gem under analysis, for adjusting the height and position of the gem within the cuvette, so that the previous set allows the correct orientation of the cuvette. The gem in the optical path of the apparatus, in order to perform the measurement of the angle of the optical axes in the bioxical gems, and other observations inherent to said apparatus.
