O Sh was founded by designer Olya Shee.

She spent many years working as a costume designer for theater and film, as well as a stylist for television.

"I’ve always been drawn to minimalist aesthetics, but I often found myself searching for that one detail to make a look stand out—something expressive yet understated, a piece that doesn’t steal the spotlight but completes the outfit. That’s exactly what O Sh grew out of—jewelry that adds the finishing touch and sets the right accents."
