Known as the revival stone, black kyanite is truly a special crystal. It has a high vibration, which translates into the ability to remove blockages quickly, and it's one of the few black stones that cannot store negative energies. Although it's particularly effective for opening the base chakra, it can be used to balance the entire chakra system, keeping the prana — or life force — flowing harmoniously.
It's a great stone for balancing yin and yang energies in the body and synchronizing the male and female aspects of your personality, especially when one is overwhelming the other. Just like selenite and clear quartz, black kyanite can be used to cleanse and amplify other crystals. Since it cannot absorb energy, crystal experts claim there's no need to cleanse this stone.
