Dogtooth Calcite

I. The Metaphysical Reading

How the stone has been held.

Dogtooth calcite is worked with as a stone of protective structure, kept in doorways and around meditation seats. Practitioners hold it as a reminder that sharpness is a form of care when it is directed at what is trying to slip past.

II. The Scientific Reading

What the lattice actually does.

Dogtooth calcite is a habit rather than a species — sharply pointed scalenohedral crystals of calcium carbonate whose double six-sided pyramidal terminations resemble canine teeth. It is characteristic of low-temperature hydrothermal veins and cave environments, where slow precipitation from CaCO₃-saturated groundwater favours this pointed scalenohedral form over the blockier rhombohedron.
