Galena

Galena is a PbS mineral and the principal ore of lead. It it spans ancient cosmetics and metallurgy to modern mining; lead content imposes strict safety limits.

Its physical identity is distinct from spiritual interpretation. Its weight and gravity associations link it with shadow work and boundaries. 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. Because it contains lead, do not create dust, keep it from children, wash hands after handling and never place it in water.
