I think this may double as a lid for a #22 bottom.
An 8-inch diameter typically corresponds to a vintage size #20 in classic French cookware sizing metrics. The ribbed, circular pattern on the bottom dates this specific style of Le Creuset or Cousances casting between 1939 and 1957. The exterior color appears to be a pastel shade, likely Paris Blue.
