Jewelry for urbanists has taken a new turn with these silver, gold and platinum cityscapes, each featuring iconic buildings, monuments and landmarks from major metropolitan centers around the world.

Ola Shekhtman, a goldsmith from North Carolina, has crafted rings around cities including San Francisco, Boston, New York City, Paris, Amsterdam, Stockholm, Berlin and Hong Kong, selling them online via Etsy.

Growing up in Siberia, Ola wanted to travel the world, eventually visiting London and San Francisco before moving to New York.

With the help of 3D-modeling software, she created this series to capture the spirit of places she has been and those she yet wishes to visit. Buyers can likewise decide whether to pick places they live, favorite past points of travel or goal-oriented rings for desired future destinations.

The individual structures are impressive as is the fact that they have moving parts, but their rate of construction is particularly compelling: the man behind this project is creating an additional mini-building each and every day.

Charles Young has an advanced degree from the Edinburgh College of Art where he learned to make models – this project was a challenge to himself to not only remain continuously productive but to continue to improve his craft day by day.

With fresh posts every day, Paperholm represents a growing micro-troplis populated with buildings, buses, cars, planes and trains, the motion of which is animated via gif-formatted images.

But the movement goes well beyond vehicles and into the realm of rotating radar dishes, spinning flywheels, sliding cranes, opening and closing garage doors and other elements that give this growing urban experiment a sense of life.
