This is a two bracelet set. One bracelet is for your main seven chakra to help balance them out & protect you from unwanted energy. The other bracelet is a clear quartz bracelet for clarity while balancing your chakras out. 
What are chakras ? 
Our body has 114 chakras yet only 7 Chakras of the body that are advancing alongside the spine, are considered as the foundational chakras. The 7 Chakras symbolize energy centres and correspond to a bundle of nerves, major organs, and areas of our spiritual body that impact our physical and emotional well-being.
