An optical test instrument used in gemstone study to examine internal structure, stress, and crystal behavior is called a polariscope. In order to differentiate between natural and synthetic gems and identify internal pressure or methods, it helps gemologists in studying light patterns within stones. Accurate measurement of quality and safe handling during cutting and setting are provided by this safe method. Gemology labs and training facilities frequently use Perfect Group India's polariscope instruments because of their clear observation, easy use, and constant performance.
