This design can be made any size by simply adding or taking out lave beads. The beads chosen to represent the chakras are: 
Crown Chakra (purple) is Amethyst, Third Eye Chakra (indigo) is Lapis Lazuli, Throat Chakra (blue) is Blue Kyanite, Heart Chakrs (green) is Green Jade, Solar Plexus Chakrs (Yellow) is Yellow Jade, Sacral Chakra (orange) is Chalcedony, and Root Chakra (red) is red coral. The Black Lave adds the element of grounding and protection, and the Selenite bead helps keep the bracelet cleansed and charged. The OM charm represents the cosmic vibration that underlies all existance, it promotes a more quiet mental state, reduces stress and improves attention span.
