Iconic arc-en-ciel by Andrea Bellosi for Studio Alchemia , Italy circa 1980.
Rare original projector light from white marble, metal and prismatic glass.
It projects a rainbow in multiple sizes depending on the distance.
It’s also dimmable and hence one can dim the rainbow. It’s marked (in the metal handles).
The condition is good, some minor chips on the marble in the base area, one chip on the prism.
The lacquer is still nice. Dimensions are: 9.44″ x 7.87″ x 8.66″.
