This is a lovely vintage perfume bottle made of blue crystal glass, most likely of Czech origin, but possibly German. I believe that it dates to the 1930s art deco era. It has a separate base or stand, which makes it even more interesting. It measures 7 1/4 in height exclusive of the base and 8 in height including the base. It is in very good condition - two fleabites to the raised facet on one side of the stopper and a tiny chip to the corner of the base - all visible in the close-up photos but really but at all noticeable under casual viewing.
This is a lovely display bottle - pretty colour and nice quality!
