How is Optical Calcite used in meditation?
Optical Calcite is primarily associated with the Soul Star and Third Eye chakras. It is used by practitioners to enhance mental clarity, clear energy blockages, and amplify positive intentions during manifestation.
What makes Iceland Spar different from regular Calcite?
While both are calcium carbonate, Iceland Spar is the completely transparent variety. It was historically used as a Viking navigational tool due to its ability to polarize light.
