Spirit Quartz, also known as Cactus Quartz or Porcupine Quartz, is a unique variety of quartz that is formed from a central quartz core that is encrusted with smaller quartz crystals, giving it a spikey, cactus-like appearance. The purple color of Spirit Quartz is due to the presence of iron and aluminum in the crystal's composition. The intensity of the color can vary, with some crystals being a pale lavender or lilac, while others are a deep, rich purple.
