Leonid, Looking at a diamond that has ideal cut, 1.2 on HCA, with a 0.9% culet. Is the culet too large? At what percentage does the culet play a factor in the brilliance of a diamond? Thanks, Alex |

Hi Alex, I am the HCA 'H' The culet can go to 10% before any radical effects are detected by the GIA's virtual computer modeling research. However this would look like a I3 inclusion and  Treat the culet like an inclusion, and at that % the size of the diamond would need to be 20ct before I would be concerned. Dave Atlas likes a very small to small culet because it minimises risk of chipping during handling and setting. Garry Holloway |
