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  Igneous 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 

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!
