This is the first book that deals with the economics of diamonds, specifically with the determinants of diamond prices. The period of 1978-1983 was chosen to shed light on the dramatic drop in diamond prices. Khoury clearly identifies these determinants, distinguishing them from one another by the level of impact they have on diamond prices. The book includes: a quick review of the characteristics of diamonds, the financial performance of DeBeers in a declining market, the economic structure of the diamond industry, the method for exercising economic control over the diamond market, the economic variables influencing diamond prices, and the modeling of diamond prices and the testing of the model using advanced statistical methods.
