I. The Metaphysical Reading

How the stone has been held.

Mugglestone — the trade name for tiger iron — is worked with as a stone of grounded courage and steady vitality. Its three interlaced layers are said to bind physical strength, willpower and clarity into a single practical current.

II. The Scientific Reading

What the lattice actually does.

Mugglestone, or tiger iron, is a banded metamorphic rock composed of alternating layers of red jasper, silver-grey hematite and golden tiger's eye. It formed in Precambrian banded iron formations of the Pilbara region of Western Australia, where fibrous crocidolite has been silicified into tiger's eye between iron-rich bands.
