Undefined Jewelry

Undefined. was initiated in NYC by designer, Kiera Junghyun Kim in 2017. Operating between Seoul, South Korea and NYC, all jewelry is handmade/handcrafted in New York City, using thoroughly-selected materials.




Genderfluid, handmade jewelry brand based in New York. Undefined. challenges traditional concept of fine jewelry and designs by freely navigating precious materials, method of communication and design that makes our creations boundless.

We have been investing in high quality materials and craftsmanship, as this is fundamental to the core value of our brand. All choice materials and precious metals are sourced and made by hand locally in New York City.

Not just another jewelry brand, Undefined. has also devoted itself into being a platform to connect artists with resources that could help them build their own brand, be it with manufacturers or management.





I started a brand called Undefined, built on exploring ideas of versatility and fluidity through⁠ collaborations with artists around the world.

Growing up in South Korea, I’ve been constantly confronted by societal pressure to conform and limit my identity and ideas. It has taken a long time to find myself in the world; having the confidence to stay true to myself. I am now professionally in a place where I can express ideas of being fluid and non-conforming. I want to take this fundamental freedom of Undefined into the future, and I hope that one day, my platform can also help others feel natural and confident
