The Woman Behind the Brand

From Dublin Roots to a Global Vision


Sadhbh Roux-Fouillet, the designer, founder, and creative force behind Isabella Roux, was born and raised in Dublin, later honing her skills in London. Now based in Geneva, she carries with her the influence of Ireland’s west coast — its golden light, untamed landscapes, and deep sense of history.

Trained at the Royal College of Art in London and experienced in working with leading jewellery houses across Europe, she founded Isabella Roux in 2018 to create pieces that blend meaningful storytelling with refined craftsmanship. For Sadhbh, jewellery is more than adornment — it’s a bridge between personal history and artistic expression.


The Story and the Secret

Jewellery with a Soul

At the heart of Isabella Roux lies a deeply personal design process. “The bespoke process is my favourite part — connecting with people, listening to their stories, and designing a piece that reflects something real and personal,” Sadhbh explains.

Every creation begins with a conversation and evolves into a one-of-a-kind jewel, handcrafted in collaboration with expert European artisans. This approach ensures that each piece carries not just beauty, but meaning. She believes jewellery has a quiet power — to strengthen, to uplift, and to make the wearer feel like their most confident self. That emotional resonance is what sets Isabella Roux apart.

Design DNA

Bold Simplicity and Lasting Meaning


Isabella Roux jewellery is defined by its bespoke spirit, sculptural forms, and a harmonious blend of tradition and modernity. Clean lines, luminous hardstones, rich colours, and the poetry of nature all shape her work. Pieces may feature a detachable beaten disc charm, a string of pebble pearls, or the subtle texture of a hand-finished surface — details that feel both timeless and contemporary.

Whether customising an existing design or creating something entirely new, Sadhbh’s aim is to craft jewellery that is “quietly powerful, emotionally resonant, and unmistakably personal.”


"I deeply believe that jewellery can hold power — it can strengthen, uplift, and help you feel more like yourself" - Sadhbh Roux-Fouillet. Designer, Founder & Creator

Craftsmanship and Values

Sustainable Practices with Integrity


Sadhbh’s commitment to sustainability begins with her makers — small European workshops she has nurtured relationships with for years. Materials are responsibly sourced, with clients offered the choice between natural and lab-grown diamonds. Both are ethically sourced and equally beautiful, but each holds its own significance, allowing the wearer to select what feels most meaningful.

By prioritising quality over quantity, Sadhbh releases a small new collection once a year, focusing most of her time on bespoke commissions. “It’s not just jewellery,” she says. “It’s an invitation to embrace your power.

Why we love it

We admire Sadhbh for her ability to create jewellery that speaks to individuality and inner strength. Her designs don’t chase trends — they feel grounded, timeless, and personal.

There’s something undeniably compelling about the way she works: slowly, intentionally, and with a genuine love for her clients and collaborators. From the windswept shores of Ireland to the ateliers of Europe, her pieces carry a story of heritage, artistry, and human connection. Sadhbh doesn’t just make jewellery; she creates heirlooms that whisper strength and beauty to those who wear them.
