I. The Metaphysical Reading

How the stone has been held.

Cassiterite is worked with as a stone of long-term craft and material inheritance, favoured by makers who work with metal and by anyone learning a skilled trade. Practitioners speak of it as a stone that rewards patience over cleverness.

II. The Scientific Reading

What the lattice actually does.

Cassiterite is tin dioxide and the principal ore of tin, mined for over four thousand years and central to the Bronze Age tin trade of Cornwall, Brittany and Iberia. Its very high density and adamantine lustre distinguish it from most other black minerals. Modern production is dominated by placer deposits in Malaysia, Indonesia and Bolivia, and by hard-rock mining in DR Congo, where the material is a conflict-mineral concern.
