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.Peter M.
