BORN FROM LOVE

KOSINER began with George — a father who wished for earrings his daughter could wear without worry. When a pair once caused irritation, he realized beauty should never demand tolerance, only trust — jewelry should feel safe enough to wear all day, so comfortable that you forget it’s there.

WHERE WE COME FROM

Born in Hong Kong and now operating from Irvine, California,
we are a team who loves jewelry deeply — not for ornament alone,but for what it touches, who it protects, and how it becomes part of life.

KOSINER exists because one father wished to make jewelry
that his daughter could wear freely, comfortably, without fear.
And today, we extend that same protection to everyone.

MADE FOR COMFORTABLE WEAR

Our jewelry is crafted from tested titanium, silver, and gold,verified by Intertek through random-sample testing to meet California Proposition 65 standards for everyday skin contact.

Free from lead, nickel, chromium, and other skin-irritating metals.
Lightweight, skin-kind, gently polished —
something you forget you’re wearing.

SUSTAINABILITY WITH CARE

Carbon-neutral shipping, FSC-certified packaging, recycled metals,
every decision is thoughtful — because comfort isn’t just for the body,
it’s for the world we live in.
