Indigo Gabbro (occasionally referred to as “Mystic Merlinite”) is a remarkable stone that comes from Madagascar.  Indigo Gabbro was formed on a power-spot, and accordingly, contains strong amounts of the “centering vibration,” making it a rare member of the class of adaptogenic stones.  Indigo Gabbro also contains the vibrational qualities of Black, Indigo, and Violet.  These vibrational characteristics give Indigo Gabbro the ability to absorb detrimental vibrations and alchemically transmute them into the centering vibration.  Indigo Gabbro is the closest thing to a self-clearing stone that exists today (it is still a good idea to occasionally rinse it with running water to remove dust and other surface contaminants).
Indigo Gabbro’s unique transmutation properties make it a great resource to harmonize detrimental vibrations from EMF sources, such as electronic devices and Wi-Fi routers.  Simply place the stone on the power chord of whatever device you intend to correct.
I’m often asked what my favorite stone/crystal is.  My answer is always unequivocally Indigo Gabbro!
Please note that another form of Indigo Gabbro exists that comes from Alaska.  However, it does not contain the centering vibration found in the source from Madagascar.  At Grand Harmony Vibrational Medicine.  We vibrationally test each piece sold for authenticity and to ensure it contains the beneficial centering vibration.
