I. The Metaphysical Reading

How the stone has been held.

Jade is worked with across Chinese, Mesoamerican and Māori traditions as a stone of continuity between generations, held for steady prosperity, safe travel and calm judgement. It is said to soften harshness in the carrier without asking them to become naive.

II. The Scientific Reading

What the lattice actually does.

"Jade" is a cultural name for two distinct rocks that pass the same use test — extreme toughness from felted interlocking crystals. Nephrite is a fine-grained variety of the amphibole tremolite–actinolite series; jadeite is a sodium-aluminium pyroxene, generally harder and denser than nephrite and the only kind that occurs in the vivid "imperial" translucent green. Both are worked in carving because the interlocking microstructure resists fracture even at edges thin enough to translate light.
