Gems of vivid green emeralds are formed in special geological settings. Deep under the Earth, where extreme pressure and temperatures enable the ideal combination of elements to crystallize, are where these valuable stones form. The distinctive green color of the Vivid Green Emerald is caused by the presence of vanadium or chromium throughout this process. These jewels gradually rise to the surface due to tectonic action over millions of years. The resultant stones are frequently discovered in old riverbeds and metamorphic rocks. The toughness and beauty of these brilliant green emeralds are demonstrated by their journey from deep beneath the Earth to the surface.
