In the traditions of lithotherapy and certain cultural practices, this material is associated with the following themes: alignment, expression, and clarity. These associations are cultural, spiritual, or personal reference points. They do not describe an effect produced by the stone.

Kyanite in jewelry

Its elongated crystals and blue shades are sought after for pendants, earrings, and cabochons. Its cleavage and directional hardness require careful cutting and protection against impacts.

Care: Use a soft cloth and a brief cleaning with soapy water. Avoid ultrasonic cleaners, steam, and impacts.
