What do blue crystals mean?

In the crystal-healing tradition, blue crystals are the stones of communication and calm. Cassandra works with them at the Throat chakra for clear speech, truth, and peace. Lapis Lazuli, Sodalite, and Aquamarine are classic choices.

Color meaning

The meaning of blue crystals

Blue stones carry stillness and clear water. In my practice they are the stones for the throat, for saying the true thing, and for cooling an overheated mind.

Traditionally linked to the Throat chakra, blue crystals are read as supporting honest communication and calm. Lapis Lazuli was prized in the ancient world as a stone of truth and royalty.
