When it comes to jewellery, the industry is constantly evolving, offering new technologies and materials that are changing the way we design. A wave of young jewellery brands are reimagining the art-form, abandoning traditional shapes and styles, and playing by their own rules. But every so often, a brand comes along that stops us in our tracks, creating industry-changing pieces that pave the way for a revolution. THE RAYY fits into this space, being the creators of the world’s first ‘light-shaping’ fine jewellery, that pushes the boundaries of technology and design, and sparks a conversation — and we mean literally.
Launched in 2019, THE RAYY is a Switzerland-based fine jewellery brand that fuses scientific innovation with superior Swiss craftsmanship, creating avant-garde jewellery that sets a new standard for creativity. The brand offers infinitely customisable, ethically made gold rings and pendants, that use cutting-edge technology to reflect sunlight and reveal hidden messages within their surface. Born out of scientist co-founders Yuliy Schwartzburg and Romain Testuz’s fascination with sculpting light, the brand’s ingenious pieces are a powerful means of expression, giving wearers the unique ability to project a thought, share a meaningful idea or date, and most importantly, express their individuality.
The jewellery is beautifully designed too. Informed by clean lines, minimal shapes and abstract details, THE RAYY’s pieces are the work of creative director Noémie Arrigo, whose subtle yet standout designs speak for themselves, while allowing the light to shine. Exuding a sensibility and style that is both modern and timeless, and consciously made of responsibly sourced materials and lab-grown diamonds, their inspiring creations have redefined the future of fine jewellery, and are kind to the planet too.

What lead you to create THE RAYY?
Romain: It all began at the Swiss Federal Institute of Technology in Lausanne, where I was researching into the ability to control or ‘sculpt’ light with fellow scientists Dr. Yuliy Schwartzburg and Prof. Mark Pauly. There, we developed and patented a never-before-seen technology, that alters the way light reflects on different surfaces. It allowed us to create invisible engravings, that when touched by light could reveal hidden messages or images — and the possibilities are endless. It was an exciting discovery that would enable different industries to shape light and personalise their products. But we always knew we wanted to create our own brand, and build a product that was designed around the technology, rather than adapting to it. It was through meeting talented jewellery designer Noémie Arrigo, that we realised the unique potential for jewellery to bring to life our prototype and showcase the innovation — leading us to partner together in 2019 and launch THE RAYY.
Noémie: My main source of inspiration is the beauty that is found in simplicity, which blends into my obsession with clean lines and minimal shapes. With a background in graphic design, I have always been interested in experimenting with abstract outlines and silhouettes, creating modern designs that are understated, yet full of character. With THE RAYY, it was a challenging yet exciting opportunity to create jewellery that was beautiful and intriguing—beyond its ability to project light—whilst having the right size and surface area to allow the technology to function. It was really the coalescing of science and art, and a quest to create minimalist pieces with personality, that defines our jewellery today.
