Tibetan Quartz
Tibetan Black Quartz is believed to be a powerful stone with purifying energies and the vibration of the "OM". It is called Black quartz because it often has black inclusions, although clear examples exist too. It is reputed to be good for balancing all chakras and meridians and also for very powerful energy grids and deep spiritual meditation. Tibetan "Black" Quartz is also thought to be excellent for dissolving energy blockages and purifying energies. Itt is also said to protect & purify the aura & environment & so is often used in the corners of a room for purifying energies and protecting the space from negative energies.
