I like it, but I can merely speculate about origins. There are some details that make we wonder whether a Czech origin is correct, like the polished rim, which feels un-Czech to me. Also, I have some brown Czech pieces of the 50s-80s, and the colour of yours doesn't really match. Unless it's much younger than that, at which point colour comparison doesn't really work anymore.
If it's not a modern vase, but a 50s-80s piece, that would stylistically leave some options like Scandinavia, Germany, France etc, but somehow my (sometimes erroneous) first guess would be Belgium or France. The lobed form, the way it goes from lighter at the bottom to darker at the rim, and the polished rim remind me of 60s-70s Belgian glass, but I have never seen that colour used there, so maybe I'm way off.
