Amethysts are reported to open a person’s third eye. The third eye is considered to be a source of power and wisdom.
Crystal practitioners believe a person can use amethysts to enhance or sharpen spiritual visions and enlightenment.
Metaphysical crystal practitioners may also believe that amethyst geodes or crystals placed in your home will absorb negative energy and create an air of tranquillity in the space.
 Plus, they claim that amethysts help block electromagnetic frequencies and “geopathic stress” that can foster negativity. This is said to occur when human-made objects disrupt the earth’s natural energy.
