Product Description

A diffraction grating spectroscope is one of the classic instruments found in every professional gemological laboratory. By examining the absorption spectrum of light transmitted through a gemstone, the instrument can reveal diagnostic spectral lines that help identify many natural and lab-created gemstones. Its compact size makes it ideal for carrying in a gemological toolkit while providing the optical quality required for professional work.

Why Professionals Choose This Instrument

Spectroscopy remains one of the most valuable nondestructive tests available to gemologists. Many gemstones exhibit distinctive absorption patterns that can assist in confirming identity, detecting treatments, and separating similar gem materials. Whether you’re a professional gemologist, jewelry appraiser, student, or serious collector, a quality spectroscope is an indispensable addition to your laboratory.
