diamond photorealistic color images in different lighting conditions.

After the optimized proportions are fixed for each shape, these shapes are optimized to fit in the piece of rough. Some stones became smaller, other - bigger. In this example after this stage only two shapes remain: oval and radiant. One can compare both by DC photorealistic images and by color metrics.
