This looks very 60s Germany to me. Peill & Putzler for instance used this sort of clear-and-etched technique a lot, but their vases are usually marked on the base or close to it by a small double P logo. If someone sold this to me and tried to convince me it was a 60s Peill vase by Horst Tüselmann, I wouldn't have a great deal of trouble believing it

.
But other German makers, like Nachtmann, made similar designs as well. As postwar German glass isn't the best documented, it can be difficult to pinpoint it to a specific maker.
Nowadays this sort of clear-and-etched isn't made in Germany anymore that I know of, but it could of course have become fashionable in other parts of the world (especially if you have reason to believe from lack of wear that it isn't very old).
