Spectroscopy is the science of analyzing the way light breaks into its component colors. By analyzing these different colors, we are able to determine a number of very specific properties in the gemstone being studied. Depending on the type of spectrometer we use, the varying test results will help determine not only the chemical makeup of the gemstone itself, but specifically, where it gets its color from, whether the gemstone is synthetic or natural, if it has been treated, and even what part of the world it is from.
