Kambaba Jasper, also known as Kambaba Stone or Green Stromatolite Jasper, is an extremely old stone dating back to 3 billion years ago. 
 
Kambaba Jasper is actually not a Jasper, but rather a fossil.
 
Kambaba Jasper is a very energizing stone that activates our root and heart chakras. It helps provide much needed healing to the heart and calming of negative emotions such as guilt, trauma, grief, jealousy, anger, and sadness.
