vintage cobalt blue glass dishes, dinner and salad plates set for 4

Deep cobalt blue colored glass plates - four each of dinner plates (about 10" in diameter) and salad plates (about 8 1/4" in diameter), all in very good condition showing very little scratching or use. These aren't marked at all that we could see. Maybe Arcoroc? Crisa? Kig? Crate and Barrel?
