Does anyone know why this is happening? The heart of the problem is that it will only render some of the polygons (ie the noisy things in the image) and nothing else
Mostly the problem is that I can’t get past the bugginess
can you upload sample file so we can looks at it
salutations
Could it be that we see default greyish World light mostly in this picture? Turn it black, use light emitting planes to light diamond.
See this result/material node setup too.

You’re still on blender 2.59… :(. I would suggest getting a fresh one… Cycles since then had advanced a lot.
Two things can happen. The refractive/reflective material needs background things (lights, background objects) to reflect or refract. Sometimes you also need to increase the number of bounces, in this case transparency bounces, to make light reach all faces of the object.
btw the cycles installs for windows are on graphicall right?
would 1024 suffice? or are we talking more cuz it’s still only rendering a couple triangles
Oh, and btw change normals direction…
I found other cycles dispersion setups at Blendswap:
The render image looks fine
Can anyone tell me how to build one from scratch ?
what do you mean ?
