Most are stamped on the bottom Nessa Gaulois, Miami Beach but some are not. Internet searches describe it as Nessa Gaulois designed by Sascha Brastoff. A rare find especially in these colors.
I have seen a few of the Pink "Surf Ballet" online but this set is a platinum marbleized design. No chips, cracks or repairs.
46 pieces to include 8 oval dinner plates (11''), 8 salad plates, 6 bread plates. 4 cups, 8 saucers, 8 salad bowls, 1 large salad serving bowl, 1 elongated server, 2 items I'm not sure what they are; maybe for oil and vinegar.
Even though none of these are signed Sascha Brastoff online research shows it was designed by the artist for Nessa Gaulois. Again not an expert in this dinnerware just reporting what I've researched.
