This piece is filled with rainbow. There is a water clear smaller quartz seemingly floating and sitting ontop of the larger quartz formation you see as the center point of this piece.
 
I have personally found that colombian quartz packs a lot of light in them. These quartz are powerful clearers and often times they love sitting in a sunny bright window.
 
Excellent for all chakras and is great for meditation, dreamwork, healing, communication with Spirit guides, focus, and stimulating the imagination. Quartz is a multidimensional stone and it is up to the user to work with quartz to see what energetic gifts it can bring into your life.
