A vase with the characteristic shape of the Diapason and an imposing size. The side, in clear crystal, is traversed by a dense weave of vertical and horizontal engravings made entirely by hand by master engravers, while the infinite facets deriving from them create a play of parallel prisms. As if in a crucible, the light collects and concentrates to then be poured onto the base in precious black crystal, a luminescent cascade radiating into the surroundings.
