It reminds me of the Desna "3 graces" vase I have. Desna has reused lots of old moulds. Your glass may be more original than mine which I know is modern. Note the 12 sided base on mine - I suspect yours has one the same. I have seen Desna in pale blue, greeny-yellow(similar to yours), amber, malachite(a dark swirly green) and a lapis(dark blue)colour.
