Beschreibung
Zusammenfassung:	Some examples herein include systems and methods of creating standards of gemstones of various classifications, which may display certain characteristics of the various classifications when excited by ultraviolet radiation and fluoresce in response. In some examples, a set of standards are created using fluorescent material, filters, and a radiation source to compare against a sample gemstone. In some examples, specific Light Emitting Diodes are selected to illuminate the gemstone samples under analysis.
