Each stone and crystal has metaphysical properties that can help aid in specific situations, help boost certain body functions/body parts, and can even offer different insight into the seen and unseen world around us.
 
Carnelian: It is a stone of creativity, individuality and courage and protection. It can aid memory, including recall of past lives. It can assist one in finding the right mate as well as protect oneself against anger, jealousy and fear. In addition it can help with manifestation of one's desires, and brings good luck. 
 
Celtic Knot: Comes in many variants and versions but traditionally they all symbolize the connection with all of humanity and life on Earth. They are symbols that remind us to not only be kind and understating to one another but also that we are all woven from the same cosmic cloth. The Celtic Knot also serves as a symbol of good luck and protection.
