I. The Metaphysical Reading

How the stone has been held.

Nundoorite is worked with as a stone of protective grounding, deep sleep and shadow work. Its dense green-black tone is said to steady the nervous system when facing what is usually kept out of sight.

What the lattice actually does.

Nundoorite is a rare rock composed principally of the sodium-iron pyroxene aegirine intergrown with albite feldspar. It was described from the Nundora area of New South Wales, Australia, where it forms in alkaline igneous intrusions.
