Quartz, in its pure type, is colorless or white, however variations containing impurities can show colours like pink (rose quartz), purple (amethyst), or yellow (citrine). This variation makes identification based mostly on colour alone unreliable, but it contributes considerably to the aesthetic worth and geological understanding of those supplies.
Understanding the components affecting mineral coloration permits geologists to deduce the presence of particular parts and the geological processes that shaped the rocks. This information is essential in fields like useful resource exploration and environmental science. Traditionally, the various colours of stones have captivated human curiosity, resulting in their use in jewellery, artwork, and structure since historic instances. The distinctive look of particular stones even contributed to their cultural and symbolic significance throughout varied societies.
