Today we had our second class in GEOL1030-010 and discussed minerals. Not only are minerals important as resources, but they are beautiful. Check out this link for some amazing photos of minerals.
In class, we also discussed diamonds and why they are so expensive. Part of the reason is thought to be that the De Beers Family of Companies controlled the supply of diamonds throughout much of the world in the 20th century and through monopolization controlled prices. In 2004 De Beers pleaded guilty to price fixing and paid $10 million to settle the indictment (see here). The charges brought by the Justice department in 1994 were keeping De Beers from directly doing business in the US. That article mentions that diamond jewelry is a $60 billion business. Much of that is from engagement rings. This 2007 Slate article is an interesting look at the history of engagement rings.
