Lemurian Aquatine Calcite is a trade name for a pale turquoise blue stone from Argentina. I don't think it is actually Calcite. I have seen it called Blue Argentine Onyx but it seems likely to be a form of Chalcedony.

Whatever it is, I really love the energy. It has a very watery quality and an unusually dreamy energy. It is soft, soothing gentle bringing peace and support where there is fear, anxiety or a tendency to worry. It aids empathy and compassion and supports trust in the unfolding pattern of Life - reminding us that we are much more than our ego self. Meditating with this stone can help us to connect with our deep soul wisdom.

This stone can increase intuition and psychic ability, supporting communication with other realms and ancient memory. Like Larimar, it has a link with the Whales and Dolphins.
