Vintage Ceramic Yellow Green Thrown Vase 5" Tall 3" Wide Opening

This medium size vase seems like a potter's wheel casting, it is a heavy stoneware quality about 14 oz. The inside and out is a thick greenish yellow glaze with abstract green design around the outside. This has been in a box for 30 years, it may have been purchased in Okinowa in the 50's when Mom took flower arranging lessons.
There are a couple of places on the rim that have lost the glaze. Please look carefully at the pictures.
The vase is 5 inches tall 4-3/8 inches wide and the opening is 3 inches. There are no maker's marks.
Perfect for Dhalias or Chrysanthemums.
Thanks for looking!
