A specimen of celestite tumbled pocket stone.

Celestite, also known as celestine, is a strontium sulfate mineral (SrSO₄) prized for its delicate sky-blue color. With a Mohs hardness of 3 to 3.5, celestite is relatively soft and brittle, requiring careful handling. It belongs to the orthorhombic crystal system and cleaves perfectly in one direction. It’s softness and cleavage make it difficult to make it in tumbled form. Major deposits are found in Madagascar (famous for large, well-formed crystals), as well as in the United States (Ohio), Canada, and Mexico.

In metaphysical traditions, celestite is regarded as a stone of peace, angelic connection, and expanded awareness. It is thought to calm the mind, enhance spiritual communication, and promote a sense of serenity during meditation, as well as support sleep. Associated with the Throat and Crown Chakras, celestite is believed to aid in clear expression of higher truths and attunement to subtle energies.
