| Type : calcite Diameter : 15mm Length : 60mm Body : Metal Made in one part, same type like GIA's dichroscope The advantage of the dichroscope is that the two pleochroic colors that may be characteristic of a given direction in a doubly-refractive gem are seen side by side. 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 Operating Information : Eye viewer: Hold the upper portion of the dichroscope to your eye. Gem View: Hand hold and place the gemstone flush to the opening. The hexagonal shape at the end makes it easier to turn the dichroscope during identification. Gem Prong: Gem Place Gemstone in the prong holder into the open space as shown above. Preparation Complete Identify Pleochroism. With gemstone visible through the Gem View opening slowly turn the dichroscope exactly 1 fullrotation. Pay close attention to any color differentiation between the two small squares visible inside the dichroscope during the rotation. That number of different colors determines the refractivity and pleochroic properties of the stone. Repeat the rotation a few times to double check the count. If you do not see color changes be sure to turn the gemstone to several other angles and repeat the process above. Sometimes the pleochroism only shows on a particular axis of the gem.
