A bowl, cut into flutes.
The Ribera is one piece of MgO cement shaped like a deep, wide bowl.
Fourteen concave flutes run down its sides, and where they meet, fourteen sharp ridges rise to the points of a scalloped round top.
Fine flecks are scattered through the surface, on the top, the flutes and the edges: white on the speckled gray, dark on the speckled white.
