I like Czech glass and knobbly Berenek vases especially but I am not sure about these. It is not that they look totally wrong, the bases are consistent with some Czech style polished bases- they are hot worked designs similar to those often seen on some Czech work, but the colours are not exactly what I might expect from the vases I have seen so far, it could just be a trick of the light perhaps other photos may help...... Also the exact style plus height combination for Czech vases I have not personally seen before.
I am a bit surprised that some more experienced Czech members have missed this post. The post does not contain the word Czech? that may be an issue. Or the vases look tricky regarding exact attribution! I am not being much help I'm afraid, I would not be certain to attribute any origin myself, though they do look Czech as others have rightly said. They are really intruiging in being very near what I would expect to be Czech vases but I have not seen these before, as you may know some of the pieces are not well catalogued by collectors. You never know, hopefully some further posts will help, I am virtually saying I have no idea but they are intruiging vases! I hope something comes through, Czech or otherwise! Good luck,
