This polariscope is a compact yet powerful tool for exploring the internal light behaviour of gemstones. By revealing whether a stone is singly or doubly refractive-and by showing strain patterns-it gives vital clues for identification and for detecting assembled stones.

Designed for bench or field use, it offers stable, even illumination and smooth rotation of the stone, so interference figures and extinction patterns are easy to observe. It pairs perfectly with a refractometer, dichroscope, and spectroscope as part of a practical testing kit for gemologists, students, and serious enthusiasts. We test and pack every unit ourselves and are available to guide you on getting meaningful results from your new instrument.
