Amethyst removes negative energy from within a room. Amethyst is often prescribed to treat addiction (often in the forms of alcohol, self-indulgence, negative self-talk and more). This crystal is a stone of the sixth (third eye) and the seventh (crown) chakras: It is super high-vibration and helps us tap into our intuition and connect us to the higher planes of existence.
Scientifically, crystals are the most orderly structure that exists in nature. This means that they have the lowest amount of entropy (measurement of disorder). Crystals are structured in such a way that they respond to the inputs of all different energies around them so they oscillate, emitting specific vibratory frequencies. The way they are balanced, the frequencies they emit, and their ability to store a tremendous amount of information makes crystals essential to modern technologies. This is why crystals are used in computers, TVs, cell phones, satellites and so on.
