The key to understanding the power and potential of crystals is to look at their molecular structures. In crystalline structures, atoms and ions group together and arrange themselves internally in a regular, systemic, and symmetric highly ordered repeating pattern. Crystals have a perfect internal gemetric shape which allows them to emit a very stable energy frequency. Crystals also have the same amount of positive and negative charge, making them balanced. Some people believe that certain crystals correlate to certain chakras based on their colors, and can therefore help us with specific imbalances and blocks in our lives through the energy frequency that they emit.
Is there a difference between crystals and stones?

How can I use a crystal to positively impact my life?
- Set your intentions with the crystal
- Hold the stone in your receiving hand and ask for what you want as clearly as possible. Visualize your life once you have received what you need and how that will feel. Thank the stone and then keep it close by for a few days -either in jewelry form, stashed in your pocket, or beneath your pillow. Source: Tiny Rituals
- Wear the crystal (be sure it is touching your skin)
- Use crystals as reminders of your goals and things you want to manifest in your life.
According to Krista N. Mitchell,
…every part of our physical and energy selves vibrates at certain frequencies, and so do crystals. We can work with the vibrations of crystals that are resonant with the states we’re seeking to achieve by entraining our vibrations with theirs, or we can work with crystals that can transfer the energy we need to positively impact our systems.
