Geologically speaking, Colombian emeralds are said to be the purest emeralds in the world because Colombian emerald deposits are the only ones on earth found in sedimentary host rock rather than in Igneosu rock. The tectonic movements that created the Andes Mountains force the raw materials of emeralds—beryllium, chromium, and vanadium—found in the ground into liquid and gaseous states. These materials, in such states, find their way into cracks in the already sedimentary medium surrounding them and then eventually cool and crystallize. A saline solution found in the sedimentary rock eventually washes out impurities such as iron that cloud other beryls from forming onto the crystallizing stone. This intricate process produces the emeralds found in the mines of Colombia.

                            THE QUEEN OF THE GEMS 

An emerald is actually a beryllium stone that owes its special color to beryllium, chromium, and vanadium, all of which are chemical elements that are very scarce, and the reason for the color of an emerald. Colombian emeralds are much sought after, and not just because of their superb quality and color. A gem's value depends upon its size, purity, color and brilliance. Even when they are mined in the same area, each individual emerald has its own unique look that sets it apart from the rest. Dark green is considered to be the most beautiful, scarce, and valuable color for emeralds. But,…often beautiful emeralds that are lighter in color with good clarity and life make the most exquisite jewelry!
