Also known as Dendritic Opal, Merlinite is a stone of magic. It helps us to develop our natural magical skills, to learn magical spells, and to use these powers for spiritual enhancement. It is an excellent stone to enhance psychic abilities such as mediumship, clairvoyance, clairsentience, spiritual communication, past-life recall, shamanic journeying, and more.
A stone of synchronicity, Merlinite manifests both luck and power. It dispels negative energy and protects us from difficulty. Merlinite activates, opens, and heals the Third Eye Chakra and the Solar Plexus Chakra
