I. The Metaphysical Reading

How the stone has been held.

Garnet is worked with as a stone of committed vitality, kept close during long endeavours, physical training and the return of desire after a fallow season. Practitioners hold it as a reminder that fire in the body is a form of loyalty.

II. The Scientific Reading

What the lattice actually does.

Garnet is a group of isostructural nesosilicates with the general formula X₃Y₂(SiO₄)₃; almandine, pyrope, spessartine, grossular, andradite and uvarovite are the principal species, distinguished by which cation occupies the X and Y sites. Almandine, the iron-rich end-member, is the commonest gem garnet and forms fine dodecahedral crystals in metamorphic schists.
