The most well-known benefit of an amethyst geode is its overwhelming power to calm the mind and relieve anxiety. Amethyst crystals attract positivity and repel negative energy, both in your environment and within yourself. As the negative energy leaches away, feelings of depression, anxiety, fear, and stress will also disappear. 
Amethyst is one of the best meditation Crystals, as it helps to quiet the mind, impart spiritual wisdom and bring us closer to our inner soul. Placing an Amethyst Crystal in your home/office  can fend off negative energy and can bring peace and calm at your place.
