Ideally the most desirable hue is a bluish green to a pure green. Tone refers to how dark or light the stone is while the saturation of the colour is how dull or vivid the emerald is. Of course, you really want a stone that is rather dark with a vivid intensity, however, you may be surprised how beautiful even the lighter, dull emeralds are.
