The stone read as the word

Diamond is one element, packed in the tightest arrangement carbon can make. Its clarity is not emptiness — it is order so complete that nothing scatters. Clear is a structural condition, not a lucky one.

The same order makes it the hardest natural substance and gives it fire: every ray entering is split into colour and sent back. Clarity does not dull a thing; it makes it flash.

What it is carried for

Carried for the plainly stated decision.
Held when muddled talk must end.
