Emerald has priority over beryl as a mineral name. Emerald was known in antiquity and was prized as a gem. In the 1790s, Louis Nicolas Vauquelin, the discoverer of chromium, demonstrated that emerald and beryl were essentially the same chemical compound and that emeralds, sensu strictu, contained chromium.
