A system and method for grading gemstones, based on creation and analysis of an ordered plurality of data sets, which convey information about the gemstone's cut symmetry and proportion quality and quantity. In one embodiment of the system and method, light propagation through a 3D faceted gemstone is simulated. Facets are associated with layers by rules for grouping facets. Light movement through the gemstone tagged by layer combinations along the propagation trajectory is collected, to enable rearrangement of the simulation output data in a proposed new order. An efficient analysis of the ordered plurality of data sets is provided for cut grading the symmetry and proportion of gemstones.
