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.Pubblicazioni consigliate
