You can cleanse crystals with the crystal essence of other crystals. You do this by putting one crystal in filtered or spring water and letting it sit for 8–12 hours or overnight. Put that water in a spray bottle, and mist your crystal with the crystal-infused water to cleanse the energetic field of your amethyst. When you are finished cleansing your crystal, dry it off completely with a towel. Here are more ways to use amethyst: Amethysts have been used for vision quests and soul searches since the early days of Native American spirituality. The color blue is considered to be a helpful color when searching for answers through meditation or prayer. Holding an amethyst may help provide clarity during these times. Amethysts are also used for protection. They will absorb negative energy, so placing an amethyst on a door knob or inside a cabinet where no one can reach but you can feel safe is a great way to be prepared for harm. Amethysts are also good companions for those working with fire. They will not catch fire, but they will not affect ferroelectric materials either. Finally, amethysts are useful for alleviating stress. By holding or wearing an amethyst, you are allowing positive energy into your life. This helps keep you feeling calm and relaxed. Amethysts are very beneficial crystals to have in your home.
