Aquamarine, Maxixe-type beryl, and two types of hydrothermally grown synthetic blue beryl currently available in the marketplace were investigated by classical gemological methods, chemical analysis, and UV-Vis-NIR and mid-IR spectroscopy. These materials may be conclusively identified by a combination of these techniques. The Maxixe-type beryl (like natural-color Maxixe gem material) is distinguishable by its unusual dichroism, green UV fluorescence (when present), Fe-free chemical composition, and distinctive UV-Vis-NIR spectrum. The hydrothermal synthetic blue beryl can be discriminated from its natural counterparts on the basis of microscopic features, chemical composition, and visible and infrared spectroscopic features.

Abstract

Aquamarine, Maxixe-type beryl, and two types of hydrothermally grown synthetic blue beryl currently available in the marketplace were investigated by classical gemological methods, chemical analysis, and UV-Vis-NIR and mid-IR spectroscopy. These materials may be conclusively identified by a combination of these techniques. The Maxixe-type beryl (like natural-color Maxixe gem material) is distinguishable by its unusual dichroism, green UV fluorescence (when present), Fe-free chemical composition, and distinctive UV-Vis-NIR spectrum. The hydrothermal synthetic blue beryl can be discriminated from its natural counterparts on the basis of microscopic features, chemical composition, and visible and infrared spectroscopic features.
