I really enjoy creating grids because it gives me the opportunity to explore combinations of crystals I may not have otherwise thought to put together. I always say, there is no "right" or "wrong" way to work with crystals. I encourage you to trust your intuition and enjoy whatever combination you feel drawn to put together.
Moonstone is a stone of new beginnings. It is strongly connected with the moon and reminds us to honor the ebb and flow of our own lives. It helps us see how what we are experiencing fits into the bigger picture. Moonstone's most powerful effect is calming the emotions, which allows you to still your mind and listen to that little voice inside.
Rutilated Quartz is said to have a perfect balance of cosmic light and is an "illuminator for the soul". It is helpful when integrating life's lessons and allowing you to carry that newfound knowledge forward with you on your path. It draws off negative energy and breaks down any barriers to your spiritual progress, such as letting go of your past so you can move forward.
Selenite is extremely protective, which is an important aspect of inner work. It helps create a safe, serene space that does not allow negative influences in. Selenite assists judgement, enhances insight, clears confusion, and aids in seeing the bigger picture.
This is a combination that I have never tried before and after putting the grid together, I can clearly see how this would be extremely beneficial. No matter where you are on your journey, working with crystals is an excellent way to enhance your life.
