ClarityThe number of visible inclusions is not as critical for an emerald as it is for a diamond. The better hue and saturation are much more important. But, of course, clear emeralds are rare and valuable.
ColorIn contrast to the diamond evaluation, color is the most important parameter to distinguish emeralds. In particular, the price of an emerald will dramatically increase once you become interested in a smoothly distributed and intense tone. So, to get a lower cost, choose light and dark emerald hues.
CaratThe weight of both emeralds and diamonds is measured in carats. And in the same manner, the more carats the gemstone has, the more expensive it turns for purchase.
CutThe emerald cut can either boost or spoil the advantages of a diamond. Accurately done, it intensifies sparkling and beauty of an emerald – so, aim at ordering the one of the top clarity.
