Hi mates.
I strongly need your comments on these:

Hi, Majid. The materials look amazing, but there is some artifacting.

Are you applying Noise Reduction? If you are, I'd like to see the originals to decide if they look more natural.

amazing!

dear mates I need your critics ... BTW here is pure noisy render (in fact it is not too noisy):

I'd keep the one with the golden rings, but would give it a darker, more mirror-like background, as Fletch recommended in Tips & Tricks.

the gradient of light from light upper white to dark lower left is much better!
the reflections down into the glass are much better
if it is 'cooked' until it is crystal clear, you've got a 'winner'.

if you can get a scene demonstrating caustics in diamonds so that you can get the right lighting to get them to 'sparkle' onto the adjacent surfaces, that will be a bonus. but even in real life these 'sparkles' would take a while to set up the light properly.

To have a nice diamond sparkle or fire, one will need to take a special care with illumination. Large diffuse lights, that are needed for metals will easily make diamonds flat and grey. Tight spot lights are handy. So finding a balance in lighting is crucial.
