Concentrated

Sap reduced for forty million years until it became a jewel.

Amber · The Law of Purpose

Family: Fossilised tree resin — an organic gem, not a mineral
Hardness: 2–2.5, and light enough to float in salt water
Colour: Honey, cognac, butterscotch, rare blue and green
Signature: Preserves whole insects, flowers and feathers intact inside it

The stone read as the word

Amber begins as a running resin and becomes gem only by losing everything volatile: time drives off the light compounds and polymerises what stays. Concentration is a subtraction process.

Whatever the resin was holding when it hardened, it is still holding — a gnat, a petal, a bubble of ancient air. What you concentrate on gets kept.

What it is carried for

Carried for the single-task hour.
Held when attention must be reduced down to one thing.
