Many confuse cut with the shape of a diamond. Diamonds are cut into a number of shapes, depending on the nature or the rough stone. The most popular are round, marquise, oval, pear, heart and emerald; the choice is largely a matter of personal preference -- so make sure that what you buy suits your taste. Every diamond regardless of its shape gets it brilliancy and scintillation by cutting and polishing the diamonds facets to allow the maximum amount of light that enters through its top to be reflected and dispersed back through its top. Of all the variables affecting the value of a diamond, the cut is most crucial. All Eskimo Arctic Ice Diamonds are cut to (GIA) Very Good, Excellent or Ideal Proportions.
