As a glass designer, Lena Bergström has a clear eye for bottles. Some has an appearance making the content even more valuable, while some bottles miss that extra quality and are therefore placed far back in the bar cabinet. This is the idea of Carat City Stopper – a jewelry that can transform every bottle into a party item. The collection consists of three different glass stoppers, inspired by three different cities. Stockholm, with its straight lines, associates with the square architecture of the city center and the graphic placement of the bricks covering the iconic Sergel Square. New York has similarities to buildings from the 20s and 30s, and the cut triangle facets often visible in Art Deco decor. For Tokyo she found inspiration in minimalistic cherry blossoms and the straight dash eyes seen in Manga. The collection launched in 2009.
