[QUOTE="Dron, post: 367872, member: 7074"] Coloured [url=https://www.mindat.org/min-3337.html]quartz [/url]is usually caused by trace impurities which grow within the crystal and replace the Silicon atoms, irradiation, or are inclusions of other minerals or fluids that occurs when the crystals are growing. eg. Quartz (SiO2) + Iron (Fe) = Amethyst Quartz (SiO2) + Aluminium (Al) = Smoky Quartz High temperatures can cause coloured quartz to [url=https://www.mindat.org/photo-700718.html]change or lose its colour.[/url] Because your crystal is clear and already grown though it should be fine in the sun. Was there any more crystals where you found it? Quartz Crystals often grow in pockets! [/QUOTE]
