Nymph with Conch Shell Figurine

This is an old pottery figurine that looks like Majolica? It is unidentified and I need help with that. From what I have been able to find the woman can be considered a nymph or goddess. She is standing behind and over a conch or shell on a foliage base. It is glazed with an unglazed bottom. The figure is pale and I'm not sure if it's a clear glaze or a greenish glaze over it. The color varies from pale to vibrant. She is holding a flower in her left hand which rests atop the shell which is lying on it's side. The shell is open side up. the foliage base has green leaves and four bunches of pink and yellow flowers.The woman is wearing a blue victorian gown with an empire waist denoted with the appearance of a ribbon or belt. She appears to have green hair. The foliage pottery work is kind of knotty with sharp points.The shell has a beautiful smooth pink interior and the exterior is primarily green with a little brown on the bottom side and some blue mixed in where it is against the woman's dress. There isn't any apparant crazing. There are a few chips which I will include in photos. The marks on the bottom are pressed in to a raised rectangle - 8204, pressed into the base underneath the other number - 20 and then there is an ink mark 107...the 7 being written like european? with a slash in the center of the upright. The unglazed bottom has one hole in it.
