Prism spectroscope

Spectroscopes are a must have for a gemmologist and are used to define specific optical properties of the gemstones, for example if they are isotropic or anisotropic. Spectroscopes allow to see the absorption at specific wavelengths of gemological materials, by separating the light that passes through the gemstone in a visible spectrum.
