Locality - Orange River, South Africa Size – 45 x 32 x 24mm Weight – 30g
This natural Orange River quartz cluster features intricate crystalline formation with the main crystal terminating singly at one end and splitting into multiple spiked points at the other. The crystal surfaces are lustrously shiny and a dazzlingly bright copper-coloured rainbow reflective veil can be seen within one side of the specimen (as photographed). Quartz crystals from the Orange River region are highly regarded and sought after.
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.
