The red in this piece is so vibrant, and the cut so “commercial” that it seems almost manufactured.

Only some physical testing would tell you for sure, but it's not impossible. There was a company in New York that supplied slabs of this material as kitchen worktops and such. It was said to be a natural breccia, although I don't know where it was sourced from.

I could well believe that the dull interior of your piece would come up as that vibrant external colour after polishing and without any dyeing. It might well be a broken piece from a slab of similar material to the above that had been cut and polished for a worktop.

One test you can try is to break a small bit off and heat it with a torch to test for resin being a binder. There are some ceramic type's of similar material but by and large artificial masonry is bound by resin.
