Created

A gem that was made somewhere else and delivered here — olive-green proof that a thing can arrive already finished.

Peridot · The Law of Plan

Family: Olivine (Mg,Fe)₂SiO₄ — one of the most common minerals in the earth's mantle
Hardness: 6.5–7 on the Mohs scale
Colour: Olive to lime; the only gem colour it comes in is green
Signature: Found in meteorites — a gem that has fallen out of the sky

The stone read as the word

Peridot does not form near the surface. It grows deep in the mantle and is carried up by volcanoes, already made, already green. Some peridot is older than the earth's crust; some of it arrives inside pallasite meteorites — a finished gem, delivered.

It is also the one gem with no colour choice. Iron in the lattice makes it green and green is all it can be. Created things are like this: the intention is in them before anyone sees them, and it shows in the only colour they have.

What it is carried for

Carried as the stone of being made on purpose rather than by accident.
Worn for a light that comes from within the material, not from the setting.
Held at the beginning of a work, when the design is still underground.
