This is the beautiful marble pendant 'mass light' designed by my favorite Architect Duo from Copenhagen - Norm Architects designed for &tradition.
I quote from Contemporist
Beautiful design yet again!"When traveling cities such as Paris, Barcelona and New York, architects Kasper Rønn and Jonas Bjerre-Poulsen were fascinated by the streets lamps; the characteristic cast iron top – looking a bit like a hat – with a semi transparent glass sphere at the base.Back in the studio norm.architects detached the street lamp from its original use and transferred the shape and combination of materials in order to design an indoor pendant – the MASS LIGHT. The pendant is made of brown marble and glass, as the two architects were keen on creating a lamp made from natural stone with its warm sensual hues. The unusual use of such a massive piece of marble for a lamp gives an exceptional sense of quality and durability.
The shape of MASS LIGHT is bold, strong and masculine and yet feminine curves soften the expression. The well-known shape lets you focus on the beauty of the marble, its aesthetic structures and brown colors."
