Lovely Antique Bowl with no markings

I inherited this bowl from my mother who was a collector. i've been told by a local antique store owner that it's valuable but that's all he can tell me.  I'd love to know more about it - if it's German or where it came from and an estimated value.  There is raised gilding outling the flowers and around the edges.  There are dimensional parts to the flowers, also.  There is no mark on the back other than one short straight line.  It is very delicate but in excellent condition.

Good
