Heavy Vase with Controlled Bubble

This is a beautiful piece of glass. it's much nicer than on the pictures. The finish is light green and red. There is no mark on the vase. I have searched for hours but could not find a matching example to help identify my vase. Similar vases were identified as Czechoslovakian or Murano glass. I just hope that this is not one of the many more recent Chinese copies. If it is, the vase goes to my daughter because her cat won't be able to push this one over. It's extremely heavy.

Thanks for looking:)
