Amethyst and Black Tourmaline together make a very powerful combination to use for protection. Black Tourmaline absorbs the negative energy that surrounds you, while Amethyst guards against psychic attacks.
If you are in an uncomfortable environment, you can pair Black Tourmaline and Amethyst to cleanse and protect your auric field. Additionally, both stones are very effective for absorbing and protecting against electromagnetic smog. This means you can keep them in your living room or near your devices to mitigate their effects.
Another great benefit of this combination is that the grounding effect of Black Tourmaline can be combined with the soothing vibrations of Amethyst to release emotional instability.
