Handheld 80mm Polariscope with Flashlight Jeweler Gemologist Gemstone Tester Tool Optics Dark Field Hastings Loupe Magnifier

The polariscope is use to test cut or rough gemstones. Allows two polarising filters to observe the structure and optical properties of precious stones or minerals. It can also be used in identifying Moissanite and detecting strain in diamonds.   It can be used with a thing called a stainless sphere, (that is a glass sphere with no strain lines in it,) or a loupe. It visually shows if a stone is doubly or singularly refractive and its optic sign. It will also show strain and twinning, which will occasionally help to distinguish between natural and man made materials.
