Symmetry means balance. In diamonds’ world, it means arrangement of the facet or surfaces including its proportions and angles. To achieve better symmetry, the manufacturer has to take deep care while production. Only two things, high level of perfection and accuracy at all stages of production can result in to better symmetry. To produce an attractive diamond piece, one has to take care of better symmetry. While production, it is aimed at cutting the heaviest and most valuable diamond possible from a rough piece. This mostly means polishing a diamond with imperfect symmetry to avoid inclusions or just leaving more weight to achieve an even carat weight, such as 1.00 ct.
