I’m Rebeca Sáenz Arrarás, founder of Rebs Design Lab. I was born in Pamplona and now live in Madrid, where I personally design and create each of my jewelry pieces, combining craftsmanship with technology.

Since childhood, I’ve felt a deep passion for creating with my hands and experimenting with anything that allowed me to bring ideas to life. Technology has always been an ally in that journey—a tool to explore, repair, and build. That passion led me to discovered 3D printing as the perfect meeting point between my creative side and my technological curiosity: a universe that lets me keep learning every day while giving shape to my designs.

That’s how Rebs Design Lab was born: a space where experimentation, technique, and a strong aesthetic sensitivity inspired by nature come together. I work with materials such as PLA and PETG transforming them into organic, colorful forms.

Fashion has always been an essential part of who I am, and it’s reflected in my creations: bold, expressive pieces with strong personality. Through this project, I don’t just create accessories; I create small wearable sculptures, where technology, art, and emotion fuse together.


My jewelry is born from this fascination: vibrant colors that echo the strength of nature, fluid designs, and a contemporary spirit that turns each piece into a small wearable sculpture.


Each piece is crafted with meticulous attention to detail, from the first sketch to the final finish in silver or 18-karat gold. I believe in conscious beauty that respects the environment and celebrates the imperfect, delicate, and timeless qualities that nature offers us.

I work with high-quality materials, using biodegradable materials such as PLA or recyclable materials such as PETG whenever possible, and I prioritize working with options that do not harm the environment. I advocate responsible consumption through quality pieces, designed to last, handmade and with the care of a process that combines technique with craftsmanship.

Each piece of jewelry is the result of experimentation, constant refinement, and attention to detail. They are unique pieces, designed and created in Spain, conceived to convey emotion, identity, and character by combining technological innovation and artistic sensitivity in a creative universe where respect, art, and authenticity coexist.
