What Our Customers Say

""The silver necklace with blue-toned stones has become my signature piece. I love how it transitions seamlessly from client meetings to dinner with friends—it's sophisticated enough for work but has this beautiful artistic quality that makes people stop and ask where I got it. The craftsmanship is exceptional.""

Sarah M.

"I bought the rose gold bracelet with semi-precious stones to commemorate a career transition, and it's become so much more than just jewelry. The warm tones catch the light beautifully, and I appreciate the thoughtful design. Kate's aesthetic is truly unique—modern but with so much depth."

Jennifer L.

"These aren't the typical pieces you find everywhere. The multi-color gradient earrings are unexpected and vibrant in the best way, and the quality is outstanding. I've gotten more compliments on these than anything else I own."

Michelle K.
Chicago, IL

"I was drawn to OIYK because of the designer's background and the cultural fusion in her work. The pieces feel special and intentional, not mass-produced. My beaded statement necklace has become my everyday staple—elegant enough for any occasion but unique enough to make a statement."

Amanda R.
Boston, MA

"The attention to detail is remarkable. I love that each piece tells a story and connects to something meaningful. The mixed metal work rivals pieces I've seen at much higher price points, and the designs are refreshingly different from typical jewelry offerings."

Lisa T.

"I'm obsessed with how versatile these pieces are. I can wear my delicate threading bracelet to the office, to weekend brunch, or dress it up for evening events. The quality is beautiful, and I love supporting a designer who brings such a distinct artistic vision to her work."

Rachel H.

"I discovered OIYK through a friend and immediately fell in love with the aesthetic. The pieces have this perfect balance of modern sophistication and creative energy. My drop earrings with semi-precious stones get compliments constantly, and they've held up beautifully with regular wear"

Katherine P.

"The quality exceeded my expectations. I appreciate jewelry that can take me from day to night, and these pieces do exactly that. There's something about Kate's color work and use of mixed materials that just resonates—it's elegant but never boring."

Nicole D.
Washington, DC

"I bought a coordinated set with multi-colored gemstones for a milestone birthday, and it's become my most treasured collection. Each piece works beautifully on its own or together, and the vibrant yet sophisticated combinations are unlike anything I've seen elsewhere. Absolutely worth the investment."
