- FAST AND ACCURATE IDENTIFICATION: This jewelry testing kit is designed to measure the refractive index of and solid materials. Many consider the refractometer to be the most important of all testing instruments. The primary use of a refractometer is to measure the angle of bending or refraction of light as it passes through a .
