They say Diamonds are a Girls Best Friend, but they can be a poor rendering guys worst nightmare.
One of the reasons is the characteristic property of fine diamonds known in the gem business as ”fire” – the nice ”pretty colors”.
These stem from the fact that Diamond is a material with very high dispersion. It is also coupled with the fact that the ”cut” of a diamond is specifically made to enhance the ”fire” (dispersion) and ”brilliance” (ability to reflect light back to the viewer) as much as possible.
But even before we get to the actual dispersion part of things, lets try to see what it takes to render realistic gem’s without it first.
