Using a small mirror, reflect the light of the full moon into a small piece of aventurine (a type of green crystal) or a coin such as a nickel or a dime. This can be done either outside or near a window inside. As the moonlight is reflected into your stone or coin, imagine the object you are using absorbing the energy of the moon.
When you are done, keep your stone or coin on your person, either in a pocket or in your purse. It will attract money and prosperity to you. If its power starts to drain, simply add more to it on the next full moon night.
If you have a big piece of aventurine, you can charge it with the power of the moon using this technique and then transfer that energy to smaller items as needed. It’s like having a giant moon battery!
