This Amazing Table Is Specially Created To Look Like The Ocean

Too expensive

I would guess they just carve the pieces so they fit together, then bond them with some sort of glue.

I was thinking water jet cut and blue epoxy or resin poured in

That makes more sense, those gradations are cut pretty clean. The resin makes sense too, just stick the stone in a square mold and you're golden.

Well that's creative lol I still pictured the right image

Still 13 huh

Yep

Enjoy it. It would make a good battle setting

(If you can't see it there is a thumbs up)
