There are many variants of apatite stones; they can come in yellow, blue, green, grey or brown hues. Blue gemstones, in particular, are prized for their beauty, and blue apatite is often favoured over those of different colours. Apatite helps eliminate over-activity, under-activity, blockages and congestion in all of the chakras. It is excellent for balancing yin-yang, and for raising kundalini energy. Blue Apatite stimulates the Third Eye and the Throat Chakras.
