Sphere Collection. Designed in 2004 by architect Marco Agnoli, the collection combines the lightness of glass with the solidity of metal. Available in floor, table, wall and ceiling versions. Sphere is a modern reinterpretation of the classic crystal chandelier. The blown borosilicate glass spheres, supported by thin steel cables, crown the globular bulbs creating an effect of intensification of the light emitted. In this way, a contemporary design is created that adds purity and harmony to any environment.
