It seems that Malachite green is on its way to being quite influencial, though not just the colour (which is wickedly intense and very '40's to my mind) by the actual pattern of the stone itself. I've spotted it popping up over the last while and think it's sensational, though I've yet to commit to it 100%. Osborne & Little has two new wallpaper collections that feature both the stone and the hue. First up is Palais Chinois from a new collection called Pompadour (influenced by the Marquise de Pompadour, the fave mistress of Louis XV). That second shot is Kishangarh (try saying that three times fast) from the Indian styled Sariskar collection, featuring silhouettes of perfume bottles in Malachite. Both look very dishy in that green, though if that's all a bit too much there are safer options too. Osborne & Little is available through the design trade at Primavera.
