This natural quartz cluster features highly aesthetic formation with many excellent, distinct terminated crystals protruding from its matrix with glassy clear tips and snowy white phantoms within their stems. It has bright, shiny lustre on its crystal surfaces and sits nicely on a sturdy base, and whilst there are a few small chips and missing points, it is still a real beauty. This large cluster displays beautifully and makes an exquisite centrepiece for a crysal collection.

Quartz is the most common mineral found on the surface of the Earth, occurring in virtually every locality. Pure crystals are colourless, transparent and hard, though many are coloured by natural processes such as irradiation or by the presence of certain elements within them. These coloured varieties include the popular gemstones amethyst, purple quartz, and citrine, yellow quartz. Some quartz crystals have unique inclusions of minerals that have grown within them, such as golden rutile, tourmaline or chlorite, and others may show silvery reflective internal veils and bright rainbows. Whilst the majority of quartz is created from molten magma that has cooled and crystallized, much quartz also chemically precipitates from hot hydrothermal veins. Well-formed crystals deep within the Earth can reach colossal sizes, with some measuring several meters in length and weighing hundreds of kilograms. The largest documented single crystal of quartz was found near Itapore, Brazil, measuring 6.1 metres at its widest point and weighing in over 44,000 kilograms!
