Have you tried increasing the number of ray bounces? The default is usually too low to catch all the light, turning parts of transparent materials black where the rays have reached the limit.

ya the ray bounces were 32
gamma 1.2
samples 32
abbe number 55

I think one of the issues is the geometry of the diamonds, they need more facets.. They are too smooth at the moment so do not reflect HDRI.

In this shot I have added a diamond to show you difference.
