Malachite, a heart chakra stone, may feel like a harsher stone.  If you allow it to reveal and help you heal emotional pain, it is a wonderful stone of transformation.  As you heal, it will help you progress more quickly along your spiritual path.
 
During classes, once we were done working with the energies of Malachite, many people would put it towards the center of the table as far away from them as possible.  The energy is intense and I feel that dealing with emotional healing often makes people feel uncomfortable.  If you can move past that, this is a wonderful stone to heal past hurts, heartbreak, losses, and abuse.  It also gives you a confident strong will that can help you avoid being a victim.
 
It protects the wearer from negative energies.  I have recommended it to someone who had multiple car accidents in a few weeks, and for someone who was flying into a war zone.  It works like a cloak of invisibility.
 
Copper, which causes the green color, makes Malachite a very conductive stone energetically.  It is great for a leader since they will lead from their heart and do what is in the best interest of the majority rather than leading from ego.
 
The price is per pendulum.  Available:  2 and 3.
