This is a recent diamond education video I made to highlight the difference between the Cut quality of these 3 diamonds. I specifically selected these 3 diamonds that have almost identical GIA certificates. They all have the same grades. To a layman, these 3 diamonds are pretty much the same, but somehow perform very differently.
This video proves that you should never buy a diamond just based on the GIA certificate alone. There are many factors the GIA certificate doesn't reveal such as the light performance of the diamond.
