Grade AA genuine natural Blue Brown Pietersite beaded bracelet. Pietersite brings cleansing energy that aids you in creating change in your life. It is also known as Tempest Stone as it is a stone that carries a charge, a little like a storm raging within it. TO MEASURE YOUR WRIST: You will need a flexible measuring tape OR something flexible to wrap around your wrist & a ruler (See example in pictures). Wrap the measuring tape around your wrist, making sure to wrap it all the way around your wrist. We suggest measuring your wrist in the area you ultimately wish for your bracelet to sit.
