Howlite, a white borate mineral with formula Ca₂B₅SiO₉(OH)₅.
Also known as: havlit · howlite
Howlite is a white borate mineral with formula Ca₂B₅SiO₉(OH)₅. It its porous nature makes it commonly dyed as turquoise imitation, requiring disclosure.
Its physical identity is distinct from spiritual interpretation. It is associated with simplicity, pausing before reaction and evening rituals. These correspondences are symbolic uses in modern crystal culture, not measured mineral effects.
Because of its low hardness it should be protected from scratches and impact and cleaned gently with a dry, soft cloth. Spiritual interpretations belong to belief and personal experience; they do not replace medical diagnosis or treatment. Mineral dust must not be inhaled during cutting or grinding.
