Re: control brightness of glass material for Diamond
If you want brighter diamonds you should try to darken all other materials in the scene (gold and ground) and then increase overall brightness via tone mapper.

I like to use low or medium contrast HDR lighting for gemstones.

Re: control brightness of glass material for Diamond
- added volumes for world and diamond
- disabled camera volume
- switched engine to bidir and sampler to Metropolis
- set color profile to filmic
- mixed with denoised image 50/50
- maybe I forgot something
That one is not denoised (probably) different lighting:

Re: control brightness of glass material for Diamond
When I try to render this with caustics, I see a huge difference between BiDir and Hybrid
v Hybrid (diamond=only glass node and gold = only metal node)
^ Bidirv Hybrid (diamond=only glass node and gold = only metal node)

Re: control brightness of glass material for Diamond
If the diamond is gray, it means that the environment is gray (which is reflected).
Place some large area lights behind the camera so they can reflect in the diamond.
It's probably also important to have an accurately modelled "working" diamond shape (they are optimized to reflect as much light back as possible) and correct IOR (see our IOR node), otherwise total internal reflection might kill some of the highlights.
