In nature quartz crystals are regularly twinned (with twin good-surpassed and left-exceeded crystals), distorted, or so intergrown with adjacent crystals of quartz or other minerals regarding most straightforward exhibit aspect of this form, or to deficiency evident crystal faces altogether and appear to be huge.
Almost all the industrial demand for quartz crystal (utilised mainly in electronics) is achieved with artificial quartz made by the hydrothermal procedure. On the other hand, synthetic crystals are significantly less prized for use as gemstones.
