this flooring is a unique diamond sanded floor. Much like using different levels of sand paper until it becomes extremely smooth. It is then sealed with a hardener and buffed. The grinding can be deep to create a larger aggregate, like in the photo, or it can be ground down to a lesser degree. The finish shine will be the same.

That look can be achieved with metallic epoxy and adding chemicals to make them layer differently.
