Large old ceramic vase signed

This vase is really very beautiful, it is large and in very good condition, it measures 40 cm high by 20 cm at its widest. On the bottom, it is signed rd, there is also another very faded sign where we can see a "ya", it was made by hand, it is probably earthenware from desvres. The enamel is very shiny and the patterns are a little raised to the touch. A tiny chip around the top edge (photo 10). It is an old vase of good quality, it belonged to my paternal grandparents.
