Just a few vague thoughts.
I like it.
I can see age-related wear on the base, which looks from the pics to be real, so I'm not sure that China could be the origin, given the great leap in quality improvement from there is very recent.
What I have seen, that has some features in common with this, is some of the more unusual and unique bits by Adam Jablonski.
I have a wonderful vase, full of inclusions, (including embedded metal grids) and another sculpture thingy, which has a hollow and polished base like this.
Just tummy-rumbles. I'm not saying it is Jablonski, just that it might be an area to look at.
