Every piece begins with a question: how does matter behave, if you give it time?
The answer starts with Italian stone, raw earths, mineral pigments, natural binders: the same matter the Romans and the Middle Ages knew well, and that almost no one uses today. Glass is worked at the flame, without molds: it bends, it resists, sometimes it breaks, and the process starts over.
In the studio, what matters are empirical proportions, not standardized repetition. Each piece carries the time it took, the exact point where stone and glass find balance, the transformation that brought them there.
There is no line between scientific research, the working of matter, and emotional experience. It is the same gesture.

COCHLEA COLLECTION
Stone and glass in balance





Sculptural vases crafted from natural composite stone and flame-worked borosilicate glass. Separately pieces explores structural balance and material precision through hand-shaped stone elements and hand-bent glass, assembled without fixings. A contemporary expression of collectible design rooted in mineral research and controlled form.
CATHARSIS COLLECTION
A study in rupture and renewal






Sculptural objects in natural composite stone and flame-worked glass, defined by fractured geometry and controlled tension. Each piece is hand-shaped from mineral-based stone and assembled without industrial binders, combining raw material presence with structural clarity. A study in transformation through form and matter.
ROCKLUMìNA
Mineral lights





Handcrafted lamps that combine, for the first time, Italian natural rock salt and borosilicate glass. Each piece diffuses light through mineral texture and calibrated structure, creating a controlled interplay of glow and material depth. A contemporary lighting object rooted in elemental matter and precise construction.
