Porcelain figurine head

Hello all,
My friend’s daughter has been finding all sorts of antique jars that have been unearthed during construction in the backyard of their early 1900s era home. Everything is well marked and easily researched except for a small porcelain woman’s head which has been broken off of the rest of whatever it was attached to. Given the number of different jars she has found, we were thinking it may have been part of a jar top but have had no luck identifying it. Any help would be appreciated.
Thank you.

 

Thank you!

 

That's Parian Ware by the look of it. I think she was a figurine.

 

Ok. Thanks for the info. I’ll pass it on to my buddy’s daughter.
