Isabella Roux: Creating on her own terms

Isabella Roux is a fine jewelry brand founded in 2018 by Sadhbh Roux-Fouillet — a designer born and raised in Dublin, trained at the Royal College of Art in London, and now based in Geneva. After graduating with a Master's in Jewelry Design in 2013, Sadhbh spent over fifteen years working with leading designer brands and private clients across Europe before founding Isabella Roux to create entirely on her own terms.
The bespoke process sits at the heart of the brand — each piece begins with a conversation and ends with something handcrafted by skilled European artisans, shaped by the story of the person who will wear it.

The opening edit

Isabella Roux's flair for design caught our eye instantly. Meeting her, with her deliberate love of detail, confirmed she belonged in our Room.

Isabella Roux works with responsibly sourced materials, natural or lab-grown diamonds, both ethically sourced, alongside luminous hardstones and precious metals, handcrafted in collaboration with small European workshops that Sadhbh has built long-standing relationships with. The aesthetic draws on clean forms, rich colour, and sculptural silhouettes inspired by nature and the west coast of Ireland, the golden light, the windswept landscape, the deep sense of history that Sadhbh returns to whenever she is seeking creative grounding. Detachable elements, beaten disc charms, and pebble pearl details appear throughout, quiet, considered touches that make each piece distinctly hers.

Sadhbh Roux-Fouillet grew up in Dublin, trained in London, and has carried the influence of Ireland's west coast with her ever since. The quality of light there, the majesty of the landscape shaped by millions of years of nature, these are the images she returns to when she needs to find her way back to what she is making and why. She founded Isabella Roux after more than a decade working for others, driven by a clear conviction: that jewelry should hold power, strengthening and uplifting the person wearing it. A small new collection arrives once a year, but it is the bespoke commissions - engagement rings, one-of-a-kind pieces built around a client's story - that define the brand most fully.

I deeply believe that jewelry can hold power - it can strengthen, uplift, and help you feel more like yourself.

Isabella Roux's craftsmanship is entirely her own — a design DNA so recognisable it caught our eye instantly. We were drawn to her confident, unmistakable style, and meeting her only confirmed it: a genuine warmth, a deliberate love of detail, and a curiosity for jewelry that pulled us straight in. There was never any question — she had to be part of our Room.

Isabella Roux works exclusively with small European workshops, maintaining close, long-standing relationships with every maker involved in production. Materials are responsibly sourced throughout, and clients are invited to choose between natural and lab-grown diamonds — both ethically sourced and equally beautiful, each carrying a different meaning. Sadhbh's role is to guide that conversation and help each client find the option that resonates most personally with them.
