80mm Length + 28mm diameter Handheld Polariscope with Flashlight

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. Equally important and just a little more expensive. It can be used with a thing called a strainless 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.

Features:

• HEAVY DUTY and precise because it made with metal and optical glass

• Durable, reliable and made by professional craftsmen

• Gemmologist tool for diagnosing optical properties of a gemstone (singly refractive or double refractive)during usage
