AI Overview
A bench-top gemstone polariscope is an essential, professional tool used to determine a gemstone's optic character—singly refractive (SR), doubly refractive (DR), or aggregate (AGG)—by analyzing how light passes through it between two polarized filters. It quickly identifies gems by detecting anisotropy, optic axes, and strain in diamonds, making it crucial for separating spinel and garnet from ruby or identifying jade.
