About the Brand

Mociun is a fine jewelry brand known for one-of-a-kind and custom-made pieces composed of rare and unusual diamonds and gemstones. All pieces are designed by founder Caitlin Mociun and handmade in New York by trusted jewelers.

A California native, Caitlin Mociun began traveling at the age of 12, spending six years living throughout Asia and Europe, with extended stays in Malaysia and Prague, before earning a BFA in textiles at the Rhode Island School of Design. In all aspects of her work, Caitlin is inspired by the design principles of the Bauhaus. The result is Mociun’s trademark: simple, unexpected elegance.

Work with Caitlin

Mociun jewelry is celebrated for its clean, geometric forms with a playful use of color. As the company’s only designer, I hand-select all of our materials, sketch designs and work closely with our production team and our New York City-based jewelers to bring every piece of Mociun jewelry to life.
