Diamond Carat

Gemone Diamonds recommends considering Carat weight with two other characteristics:

  1. The distance across the top of the diamond measured in millimeters.
  2. The diamond’s cut grade.

It is important to measure the distance across the top of the diamond as this is how we view a stone when set into a ring. Diamond cut is also taken into consideration. Because when the diamond cut is proper in proportion it reflects more amount of light from the top. Thus, when a diamond is well cut, the light reflected out of the top makes it appear larger.

Also much of the weight of the cut diamond, hidden in the base of the diamond. Making the diamond looks smaller from its actual Carat weight would imply. It is thus possible to have the diamond of a lower Carat weight but higher cut grade. That appears larger than a diamond with a larger Carat weight, but poor cut.

Once you are sure with your Cut, Color and Clarity grade it will become easy for you to choose your diamond. Much as there are 100 pennies in a dollar, a One Carat Diamond compromises of 100 points. Hence, 50 points are equal to 1/2-carat, and so on.
