1. Things that make diamonds magical are their age (3 billion years old), the enormous effort needed to find and get them, and their magnificent way of dealing with light.
2. Lavoisier burned a diamonds completely...all that was left was carbon dioxide gas. This proved that diamonds were pure carbon.
3. The main difference between diamond and graphite are their structures. Graphite has weak bonds between layers, whereas diamond is bonded in all directions.
4. The goal of GE's project Superpressure was to make the world's first industrial diamonds.
5. The metal troilite in the meteor was important because the folks at GE hoped it could be heated and used as a solvent for graphite.
6. The GE crystals would never be gems because they were imperfect.
7. DeBeers protects the value of diamonds by controlling the release of diamonds into the market.
8. Inclusions are tiny minerals trapped at the time of diamond formation that affect the value of the diamond.
9. The man-made diamonds ended up with a brown tint because nitrogen from the atmosphere got into the presses.
10. A nitrogen "getter" chemically attracts nitrogen away from the growing diamond.
11. Faced with a potential crisis caused by the new synthetics that are undetectable under a microscope, DeBeers has been forced to look at the atomic structure of natural and synthetic diamonds to find the tiniest difference.
12. Under a UV light, synthetic diamonds glow, while natural ones do not.
13. DeBeers is putting a stamp on the diamond...a minute logo.
