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.
