Dichroic Kyanite is Kyanite bonded with Titanium and other metal molecules, producing the vivid gold, purple and blueish hues.
This is one of the two minerals in the mineral kingdom which never needs cleaning or clearing. It will not accumulate or retain negative energy or vibrations. The energy of Kyanite is unlimited in applications, making it one of the very best attunement stones.
Kyanite aligns all chakras automatically and immediately. Combined with Titanium, Dichroic Kyanite is an even more powerful crystal – with increased life force and vitality.
