Moon rock sculptural piece on wood plinth

Oh dear. I suppose I should be bigging this up in case it’s an important piece of art.
It’s best feature is that it’s small, 7” in all, so easier to hide from Hilary. A 7 foot version could be a problem.
It looks like volcanic rock or cinders and seems to be thrown or turned inside.
No signature but maybe nobody would claim it as there’s.
Ok, maybe I am a Ceramic Heathen and my apologies if I have offended anyone.
Please tell me who it is - I am genuinely interested. Thank you all again.

Hilary is my wife who has to put up with pots and stuff coming and going! Thanks, I’ll check out Beverley Bell - Hughes. Thanks

I’ve never taken a hammer to any pots before .....

I think you could be on the right track, Naomi. My initial thought was pumice, but that is formed by lava that has been fired high into the air and solidified before it hits the ground, so it doesn't tend to contain stones as Ben's piece does.
With it being on a plinth I'd guess at it being an archeologist's souvenir piece from a dig.
Ben, just out of interest, does the hole go right through the piece?

It does look like pumice but browner than the pumice I have seen. Looks a bit like slag from something like metal working. The hole goes part way - maybe a core drilled out.
So it looks like it might not be a major art piece. Could try the hammer.
