Lapis Lazuli – It opens the third eye and balances the throat chakra.  It helps to reveal inner truth, encourages self awareness, and allows self-expression without holding back or compromising.  If repressed anger is causing difficulties in the throat or in communication, it will release them.  It is also a powerful thought amplifier.
 
Black Obsidian – It is a strongly protective stone, forming a shield against negativity.  It provides a grounding cord from the base chakra to the centre of the earth, absorbing negative energies from the environment and strengthening in times of need.  
 
It repels negativity and disperses unloving thoughts. It can encourage you to face up to one’s true self, taking you deep into the subconscious mind in the process.  It brings imbalances and shadow qualities to the surface for release, highlighting hidden factors.
