The American Museum of Natural History provides a wonderful online exhibition about diamonds at American Museum of Natural History - A World of Diamonds. The diamond exhibit is well laid out for exploring the various topics, but you can also use the index below to look up specific items.

What is Diamond?

Composition: what is diamond made of?
Structure: how do carbon atoms connect to form a diamond?
Trigons: why is each diamond crystal unique?
Hardness: what does it mean to say diamonds are the hardest substance?
Durability: what is cleavage and why are diamonds not unbreakable?
Surface: why do diamonds repel water but become greasy?
Density: why are diamonds heavier than graphite?
Refraction: why are diamonds brilliant and lustrous?
Color: why are not all diamonds colorless?
Dispersion: what gives a diamond "fire"?
Flourescence: what does it mean when a diamond is fluorescent?
Electrical Conductivity: why is diamond a poor conductor and graphite a good electrical conductor?
Thermal Conductivity: why do diamonds feel cold?
Vital Statistics: all the scientific facts


Origins of Carbon: where does the carbon in diamonds come from and what is the difference between harzburgitic (peridotitic) and eclogitic diamonds?
Formation: where and under what conditions do diamonds form?
How Diamonds Surface: how do diamonds move to the earth's surface?
Where Diamonds are Found: why are diamonds found on cratons?
Indicator Minerals: what are indicator minerals?
Kimberlite and Lamproite: what do kimberlites and lamproites look like?
Kimberlite Pipes: what does a kimberlite look like inside?
Age: How old are kimberlites and diamonds?
Xenoliths: what are mantle xenoliths in a kimberlite magma and why are they important?
Inclusions: what are diamond inclusions?
Collisions and Stardust: are kimberlites that sampled the diamond stability field the only source of diamonds?
