Amethyst Clusters & Druzys are amazing energy generators. They harmonize every room (depending on the size of course, the bigger, the better) and are really amazing eye-catchers. Related to the crown chakra, Amethyst helps to have clear thoughts and mind, increases focus and concentration (work space) and helps to improve a better sleep (nightstand). The purple color is associated to spirituality and can help you to reach a deeper state in meditation. To cleanse and purify other stones, just put them in your druzy or on your cluster for 8 hours.
