My pendants are unique one of a kind pieces, no two are the same. Each crystal is hand wrapped with great care and love with black macrame cord topped with a wooden bead and sealed with a lobster clasp. These are not interchanging crystal cages, each cage is designed for the crystal it comes with. Also referred to as the "Wisdom Stone", Milky Quartz has calming and soothing properties that compare to "maternal love". With its ancient angelic wisdom, milky quartz holds and releases information; and it’s because of this that you may notice your crystal may become clearer in color at times.
