Apatite is a very interesting gemstone which has a rather unusual connection to humans – it is made up of calcium and phosphate which happens to be the most common mineral in our bodies. Perhaps this is why it can have such a profound influence on us. Apatite comes in a wide range of colours but the most common are the blues, greens and yellows. Colours have a spiritual meaning all of their own – green can symbolize growth and rebirth, blue signifies wisdom and loyalty while yellow brings joy and optimism. Blue Apatite is connected to the throat Chakra and  Apatite is not a traditional birthstone.
