The Natural History department owns a unique collection of some of the rarest and most important rocks and minerals in the world, which vary in shapes, sizes, colours and origins. From a large piece of meteorite from Arizona, to small gold nuggets from South America.
The importance and uses of rocks and minerals have grown through the ages in human civilisations. Rocks like marble were used for sculpture and architecture for its hardness and elegance, minerals such as iron and bronze were used for weapon manufacture like swords and shields, not to mention precious metals such as gold and silver fashioned into jewellery which and in turn were inlaid with various gems.
Meteorite
Meteorites-rocks or minerals that fall randomly from space- are true collector's items, since they are, indeed, rare. Fewer than ten falls are witnessed worldwide in any one year. Those that land unnoticed are usually small and only a few of these are found annually.
Pyrite – Natural Specimen, Navajún, Aguilar del Rio Alhama, La Rioja Province, Spain.
Dozens of flawless crystals of golden pyrite-which formed about 140 million years ago- burst from the face of this massive limestone matrix. The appearance of so many large crystals in such close proximity is uncommon; more unusual still is that so many of the crystals are flawless. What makes this specimen world class; however, are the crystal intergrowths –multiple crystals with cubes growing within cubes. 685 x 439 x 151mm (27 x 17¼ x 6 inches).
