MagmaLaB is an artisan studio founded in 2011 by Gaia Guarnieri and Caterina Martinelli, born from the desire to explore new forms of creation through the transformation of matter.

​

The original idea was both simple and visionary: to give new life to discarded materials, transforming them by hand into artistic objects. Over time, this vision evolved into a dedicated journey within the field of Contemporary Jewelry, where each piece emerges from a balance between aesthetic experimentation, craftsmanship, and sustainability.

 

The core material of our work is reclaimed plastic, particularly PET (polyethylene terephthalate), chosen for its remarkable qualities—lightness, luminosity, and extraordinary formal versatility. Through a series of manual processes, the material is cut, shaped, thermoformed, engraved, and decorated until it reveals a new identity.
The techniques we use — from hand-cutting to thermoforming, from pyrographic and craquelé to pigment coloring — are the result of years of study, experimentation, and research into the behavior of heat-sensitive plastics.

​

Each MagmaLaB jewel is born from a conscious choice: to create while preserving the planet’s resources, exploring the potential of materials often considered “waste” but rich in aesthetic and narrative value.
Every piece is handcrafted, produced in small series or as unique items, and bears the traces of its making: subtle irregularities, delicate color variations, and micro-engravings that make each creation truly one of a kind.

 

Our jewels tell a different story of luxury — not as display, but as the value of the artisan’s gesture, of time devoted, of attention to detail, and of respect for matter itself.
MagmaLaB is a constantly evolving studio, where experimentation meets the poetry of transformation — a place where plastic ceases to be waste and becomes once again light, form, and identity.

​

We asked ourselves how we would like to present MagmaLaB (which, after all, is us, Gaia and Caterina). And we are strange, ‘different’, someone would say. We make jewels with our hands. And we make them imagining them on other people, because we don’t wear jewels. And we make them with a strange material, a ‘different’ material, someone would say. But we study it, we process it, we transform and evolve it, creating projections of ourselves that become jewels, which tell that, in the end, nothing - or maybe everything - is different. And that’s the beauty of it. 
And it’s so natural.
