The Ostro wall light by designers Simone & Marcel is made from noble marble and comes in a range of sophisticated colours, from deep black to milky white. Its exceptional form brings to mind the ocean. The Ostro wall light comes with an oversized glass orb that highlights its shell-like form. Given the nature of marble, there will be slight variations in colour and veining between each lamp. If you choose more than one Ostro wall light, the designers ensure that they are similar in shade.
