Welcome to Oney Koontz where style, identity and a bit of magic meet.

At the heart of our brand is the belief that jewellery is more than just an accessory. It’s a statement, a mood, a memory. We design and create pieces that don’t simply decorate — they express. Whether you wear them daily or for special moments, our jewellery is meant to accompany you through life’s journey.

Our Story

Our journey began with a simple idea: what if jewellery could reflect more than trends — what if it could reflect you? Over time, we discovered that many people don’t just want a necklace, bracelet or ring — they want an expression of self, a symbol of identity, a little talisman of confidence. That’s how Oney Koontz / Caesar and Don Girl was born.

We believe everyone deserves something that makes them feel unique. That’s why we pour our passion into each design: from minimalistic classics to bold statement pieces, we aim to offer a range that speaks to different personalities and moods.

Made with Care

Quality and authenticity are our guiding values. We select materials carefully, craft with attention to detail and treat each piece as a small work of art. Our designs are created to last — so you can wear them again and again without losing their charm.

We strive for sustainability and responsibility, because we believe beautiful jewellery shouldn’t come at the cost of the planet or people.

For Every You

Just as no two people are the same — your style doesn’t have to be, either. Maybe you’re bold. Maybe you’re subtle. Maybe today you want a little shimmer; tomorrow, a quiet elegance. Our collections are designed to give you that freedom.

Wearing Oney Koontz isn’t just about accessorizing. It’s about expressing who you are.

Thank You for Choosing Us

Whether you’re discovering us for the first time or adding another beloved piece to your collection — we’re honored to be part of your story.

With love,
Ayse and Jonas
