diamond
Let an agent explain diamond as a material and gemstone, relay structure, formation, grading and uses from mineralogy and gemmology sources, describe synthetic and industrial diamond, and distinguish diamond from graphite, from simulants such as cubic zirconia and from the card suit and geometric senses.

What it is Filled
A crystalline allotrope of carbon in which each atom is bonded to four others in a rigid lattice, the hardest known natural material, valued as a gemstone in rough and cut forms including rose cuts and coloured diamonds such as pink diamonds, and used industrially for cutting, in electronics as boron-doped semiconducting diamond and in optics; diamonds form deep in the mantle, are mined and increasingly grown synthetically, and historical stones such as those recorded among the jewels of James III of Scotland illustrate their role in royal treasuries.
Why it exists Filled
Let an agent explain diamond as a material and gemstone, relay structure, formation, grading and uses from mineralogy and gemmology sources, describe synthetic and industrial diamond, and distinguish diamond from graphite, from simulants such as cubic zirconia and from the card suit and geometric senses.
Distinguishing features Filled
- Tetrahedral carbon lattice
- Extreme hardness
- Gem and industrial use
- Natural and synthetic
What robots and AI may and may not do Filled
Must not
- Sell or describe a synthetic diamond or simulant as natural.
- Help trade diamonds that fund armed conflict or evade certification.
- Overstate a stone's grade or value.
- Present one side of the debate on mining or conflict diamonds as uncontested.
Only with a human decision
- Certifying or valuing a diamond for sale, insurance or inheritance.
May
- Describe diamonds' properties, cuts and colours from gemmological sources.
- Report whether a stone has been tested as natural, synthetic or a simulant, citing the laboratory.
Moral aspects Filled
- Diamond mining has funded wars and harmed workers and communities.
- High value invites fraud against buyers.
Who is affected
- Mining communities
- Buyers
- Workers in cutting and trade
Owners Filled
Steward
The person who owns the stone; certification schemes and laboratories record its origin and grade.
Master systems
- Diamond grading laboratory records
- Kimberley Process certificates
