Pyrite, via Josh Draper: 'The thing I've realized is that, as an Architect, I really love and appreciate materials. This piece of pyrite is like an extraordinary scale model of a building. It feels like a Libeskind. The other thing is that since minerals have such incredible detail they transcend their own size and seem to describe a much larger thing. In other words, when you are looking at a mineral, it can feel like you are looking at a building.'
