Chinese Famille Rose Ginger Jar

The red seal mark appears to be overglazed and hand painted.   The jar has black delineation marks that appear to have been done first and then hand painted. You can feel the surface decorations but they are glazed over.  At a higher resolution you can see the black formations in the clay. I need to know if in fact this porcelain is true to the period or a later reproduction and it's insurance value, if any.

Thank you.

Excellent
