How beautiful are these? I came across these on Etsy. 3D printed rings into different metals celebrating city skylines. These architectural rings designed by goldsmith Ola Shekhtman make such a beautiful souvenir for some of the world's most iconic and loved cityscapes. The famous skylines include those of New York, Paris, London and other cities like Hong kong, San Fransisco, Berlin, Amsterdam and Boston. You can check out her store right here on Etsy.
