Cutting is very high quality. A 1927 Cambridge catalog has two vases which are very similar to this one. One is the 789 which looks a little fatter to me and also has a straight rim. The other is the 787 but the size listed is a little small. This vase seems to have a slight outward flare to the rim just as the 787 shown in the catalog.
The quality of the cutting is reminiscent of Pairpoint but this shape was not found in available Pairpoint references.
