Besides, index of double refraction can be also measured. Through the parameter you can judge whether a gem is uniaxial or biaxial photopositive or photonegative. The gemological refractometer is characterized by small volume and less weight. It is easy to carry. It is a popular instrument used in Jewelry market. -------------------------------------------------------Description 1)Gem refractometer, glass testing table-board, black color, C/w mini flashlight, 2ml RI liquid, manual; One year warranty Measuring range Refractive Index: 1.30-1.81 Resolution Factor: Refractive Index: 0.01 Size: 30× 70× 130mm
