Ethnic cut in grey and brown enamelled earth

I propose a cut (ideal to present fruit) enamelled clay in gray shades mainly with touches of brown. There is even a shard of red inside this cup in perfect condition (see the last photo). This very ethnic piece (probably a vintage spanish pottery) is adorned with cutouts in the shape of circles and triangles. Height of about 10 cm - diameter of 24 cm - weight of about 1, 150 kg.
