This is a lovely piece of 1960s glass. I haven't seen another vase of this particular design, but it looks like a piece designed by Frantisek Vizner. He often used the grass-like lines as part of the surface decoration of some of his pressed glass pieces, such as his famous "eye bath" vase.
It is also decorated in a random pattern around the outside of the base area with a raised bubble pattern. It has a fleur de lis mark on the base as photographed.
With a texture reminiscent of melting glass, this showstopper would certainly look magnificent in a more minimalist interior on a rosewood coffee table or bureau.
It is 8 1/4 inches in height with a diameter at the top of 8 3/4 inches. The diameter of the base is 5 1/2 inches. It is a really large and heavy piece and weighs nearly 3.2 kg unpacked
It is in excellent condition with no damage. Any white marks in my photographs are caused by reflections from the glass.
