Malachite:

Malachite is above all a very powerful protective stone. It protects against negative energies while releasing very beneficial vibrations. It is also an anchor stone, which helps to stabilize and integrate in the material dimension the influences coming directly from the higher planes of consciousness.

In the house, malachite absorbs electromagnetic pollution. Carried on oneself, it helps to lead one's life in a way that is both creative and constructive. It facilitates the connection between our physical energies and the vibrations of our subtle bodies. Malachite harmonizes emotions and helps get rid of negative thoughts.
