Exclusive to JTV! The GemVue compact polariscope is one of a series of tools that assist in gemstone and mineral identification. This tool is used in conjunction with other gem tools to narrow the range of possibilities when identifying stones and minerals. The primary purpose of this tool is to determine the optic character. Gemstones and minerals exhibit different structural forms. Some may be singly refractive, doubly refractive, or an aggregate of numerous microscopically small crystals. Each of these structures responds differently when viewed through a polariscope. This unit includes three different lighting methods which include daylight equivalent, LED, and also has a built-in sodium light that can be used as the light source to the GemVue Refractometer (GV85). Comes with a leather case and a large interference sphere. The tool operates on three different power options, a standard 120V outlet, USB power cord for you computer (both Mac and PC), or 2 CR2450 batteries. This is a valuable tool for any gem enthusiast.
