Black moonstone has the meaning of birth or new life. This is due to the ancient association that was made within certain native tribes where a black moon was connected to a new moon during the monthly lunar cycle. A new moon is the opposite of a full moon and therefore can’t be seen as the night sky appears completely void of this celestial body and black. As a new moon progresses throughout the monthly lunar cycle, more and more of the moon becomes visible and it, therefore, grows into maturity in the night sky.
Thus, black moonstone is associated with the first stage of the lunar cycle which is a new moon which is also associated with the first stage of a human’s life which is birth. With this in mind, it can be associated with anything having to relate to a sense of newness such as the first day of school or a job, the fresh start on a journey whether it be spiritual or physical, and of course a new birth in a plant or animal.
