This maybe proved a bit difficult so I will provide gradual help depending on the guesses.

This is a single image (no stacking) with a 10x objective using epi brightfield illumination with cross polarizers.

Clearly an organic structure with regularly repeating units meaning that we are looking at a colonial animal. That lowers the possible cast to bryozoan and corals. The series of vertical scratches suggests that this is a fossil specimen which has been polished, but the fine polishing has not been taken beyond what is needed to make a nice lustre for bare eye viewing. The structure of fossil bryozoan does not extend far into the substrate, whereas that of colonial corals does, so I would plump for a fossil colonial coral. Beyond that, it is not a species with which I am familiar.

There are some good points to your analysis but I will disappoint you. This is a not a plant or animal or fossil. This is something artificial.

Everybody seems stuck. Any clues, or maybe the answer?

Moulded plastic, to give the effect of "knurled" metal?

Those organic-looking outgrowths; a last-to-freeze phase squishing out from the matrix?

Ok I will provide some more help. This is a very common household item which is ''connected'' with a very powerful industry (hundreds of billions $) only in USA.
A more ''representative'' display of it's microstructure is shown in the image below.

I didn't mean USA only.I wanted to say that this industry has an enormous size of several hundred billions $ in US market.Of course there are corresponding industries all over the world with significant size.

No these images have nothing to do with leds.
