A 2d experiment, granite, granite, granite... rotten granite.
Personally I find this granite obscene.
POV-Ray, obviously, no-antialias, with minor postprocessing: contrast and
saturation.

To me, it looks almost like a satellite photo of a rocky, mountainous
countryside. I like it! :)
Does it look any 'better' with anti-aliasing?

My first thought is that the large-scale staining occurs too frequently.
Then I see that you might be using the "granite" pattern for the grains.
I find that "crackle solid" gives a more realistic appearance as it
simulates the crystalline nature of real granite. Real granite is
usually composed of quartz, feldspar and mica. The mica and feldspar
occur as crystal grains, the quartz occurs as amorphous, blob-like
grains. The quartz is a bluish white, the feldspar an off-white,
possibly pink color (I can't see pink too well), and the mica in granite
is most often a greenish or reddish copper color, but very, very dark of
course.
You might already be using crackle solid for the grains, but I can't
tell by your picture. If not, then consider finding a chunk of real
granite and studying it from a crackle solid perspective.
I hope some of this helps.

Sam, I very much appreciate your comment.
Your tips are really useful, and I will remember them when really try to achieve
a photorealistic texture.
This is actually only an (weird) experiment.
Thank you!
:-)

Some news on the *Luminous Bloom* ?
An update version?

Really?
Interesting perspective.

Oh, without antialias only to have a sort of *sharpen effect*.
Thanks for your comment!

Carlo,
I try to help when I can (even when it's not really needed, apparently ;) )

Yes, there is a new version. I never released it because I thought
nobody was interested. One person is enough for me :) There are a couple
of very minor changes I need to make to the code and then it will be
released post haste!

Luminous bloom is a miracle of code, for me (I am a perpetual beginner), and I
still have to finish to understand the mechanisms!
Oh thank you, today is a bright day!

Never assume that, Sam! Without exageration, all the utilities coming out of
your hands are highly appreciated and waited for impatiently by many from
this community. I cannot imagine a day when somebody would grumble: "Oh
dear! Another useless piece of code from Sam? When is he going to shut
down??" :-)
You certainly are one of the top creative drivers of POV-Ray.

You're welcome! The file is now at p.b.scene-files. Have fun :)

Thank you for the kind words, Thomas. The new version has been posted at
p.b.scene-files if you're interested.
