Hi and welcome.
For a flat surface you would use a normal to give the impression of
depth. Try bumps.
If you have a photograph that you want to use. You could use it as a
heightfield. Which would turn it into an actual 3D object. Where the
light colours are high and the dark colours are deep.

Here is an approach on such a material. Properly scaled it should do the job.

You may try something like :
normals{crackle -1 scale Your_Scale}
The -1 is to make it so that the normally high points become pits.
Adjust the normal depth and scalling to your taste.

Sorry to bring this old post up again. I'm just updating my collection
of example scenes I neglected since the end of 2017 now and stumbled
about this one. As all I can see, Norbert did a very good job at
answering the question of Havana7 and by resembling the image given. I
assume the image of the necklace posted by Havana7 is a photography and
I wondered how this necklace was crafted originally. Has onyone an idea?
The only technique I found so far giving similar but not equal results
is sand casting.
Best regards,
Michael
