As you place the stone, “tell” it that you want it to keep negative energy out of this space. Stones like quartz and selenite can be used to fill a space with good energy. Amethyst, smoky quartz, galena/hematite, and malachite are good stones to wear as a necklace or put in your pocket to protect from negative energy.ometimes visualization is all you need. Whether you know it or not, you have an innate ability to protect yourself from the energy that is not helpful or healthful to you. Using a visualization is one of the ways that you engage that ability. Even though you can’t remember how to create protection, your body knows.
