These are our personal favourites.  Found in Namibia in Southern Africa.  The colours are amazing. 
 
We have 3 of these rare A grade Pierersite tumblestones, in blue, red and yellow.  Each priced at $15.
 
Pietersite is also known as tempest stone as it is a stone that carries a charge, a little like a storm raging within it.  It brings cleansing energy to aid you to create change.
 
This is a crystal that is very stimulating to your energy field, and helps you to let go of unwanted habits and negative ways of living your life.
