Fine jewelry with a secret

Made of gold, diamonds and light. THE RAYY is a revolutionary brand creating fine jewelry with the hidden ability to reflect sunlight into a personal message. Designed in Switzerland, made locally with responsibly sourced materials.


In a poetic homage to the givers of light, the stars and sun, our pendant collection invites you to indulge in the wonders of the zodiac constellations by revealing your star sign in light. This collection is the result of a close collaboration with the world-renowned tattoo artist Maxime Plescia-Büchi and his studio Sang Bleu. His interpretation of the 12 Zodiac signs are projected when the sun shines on the Disk and Disk Bold pendants: a tattoo in light.

« It’s always been a dream of ours at Sang Bleu to push towards the integration of art, design and technology […] This new collection is everything we hoped for and more! »

A Unique Technology

Over 8 years of research, we developed a technology to create images in light through precise shaping of a reflective surface. When light rays from the sun, a spotlight, or even a smartphone flashlight are reflected off the jewelry, they focus to form your chosen message. A closely guarded secret – invisible on the piece itself, the message can only be revealed at your discretion.

A Sustainable Future


Rings and pendants are 18 karat gold, available in three colors: yellow, rose and palladium white gold. Sensitive to ethics and sustainability, all our gold is responsibly sourced.


Our diamonds are lab-grown and are guaranteed conflict-free, produced with renewable energy. All our jewelry is manufactured locally with the finest Swiss craftsmanship.
