London Style Dichroscope

The London dichroscope is an easy-to-use alternative to a traditional calcite dichroscope. It is used to determine the pleochroic property of a gemstone. By determining if a stone is doubly refractive it is possible to identify and separate gemstones by their pleochroic colors. The London dichroscope is constructed of high quality of material and features a lens made from two polarizing filters set at a 90^oorientation to each other.
