Can anyone identify this vase? The vase measures 24cm in height. The top dia. 13.3cm and the base 9.8cm. There is a concave pontil measuring 3.7cm. Also within the base is 3 circles of ripples, that are uneven. I am not sure if this can be seen within the pics included. I would very much like to know the originator of this such beautiful piece and the age if possible. There is clear signs of wear to the base.
