A sublime work of art designed by Gianfranco Coltella, this luminous sculpture is named after the Italian word for "small rock". Comprised of hundreds of glass elements deftly cut, polished, and assembled by hand in a smoothly sinuous shape, it is internally enriched with an LED light source that contributes to creating a breathtaking game of lights and reflections. This piece is unique and signed by the artist to guarantee its authenticity.
