This mineral is atacamite. This beautiful green colour comes from oxidised copper minerals in dry climate. Its name comes from the Atacama desert in South America, apparently one of the driest places on in the world. I want to be a midget and sleep on this moss covered bed or a couch, fluffy and smell of forests!
I had a visitor yesterday morning after the hottest night in Melbourne since 1902. This little visitor came and drank some water. Cute!
