[ [http://www.nhm.ac.uk Natural History Museum ] ]Naturally all gold has a crystalline structure, yet nuggets showing this structure are very uncommon. They require specific conditions to form, in particular space in which to grow. Crystals of gold are found in cavities in softer
mineral s such asiron oxide s, where they have pushed aside the enclosing material as they grew. Gold crystallises in the cubic system, and perhaps the most common variety is the eight-sidedoctahedron [ [http://www.sbs.com.au/gold/story.html?storyid=128 ~ Gold ~ ] ] , of which the Latrobe Nugget is a good example.ee also
