This is a stand out St Uze vase in the diablo shape in the signature blue on white stoneware with the St Uze stamp of authenticity on the base.
 
One thing that sets this apart, showing its quality, is the indented pattern around the vase.
 
This beautiful and hard to find piece in good antique condition, there is some light staining and crazing, shown in the clost up pictures, that comes with age and use. 
 
It measures just under 7" high by just under 7" diameter
