There is one similarity between them: they are all bustling with life. Full airports, big office buildings, luxury hotels. Expensive restaurants, hipster cafes, exotic food trucks. Dusty museums, modern galleries, allies of artistic anarchy. Banks, shops, gyms. Taxis, bikes, metro ... Paris, New York or London - big, dashing, constantly fascinating metropolis. In order to keep pace with them, one needs to change constantly. Even if it was to be only such a detail as a ring, an earring or a fob. "Cosmopolitan" is a collection of fully discrete metaphors carved in gold. It is a power of an urban adventure. Or of a few seconds exchange of glances somewhere on the corner of busy streets.
