How would you describe this countertop technique?

The vacation cabin we rented had this type of countertop and I liked it. I just bought a bunch of 12x12 floor ceramic tile from an individual and want to do this over my laminate countertop. Can I? What kind of grout should i buy? Sealer? Any help deeply appreciated.
