Famous Diamond

The famous American Star Diamond began life as an unnamed 14.89-carat D-color, Flawless-clarity modern round brilliant. The Famous Diamond was bought in late 1999 by the EightStar company of California, with the intent of a recutting the Famous Diamond. The plan was to prove, on a large scale, that the EightStar approach brings otherwise unattainable sculptural and optical perfection to the round brilliant, even ones the rest of the world already thinks are as good as it gets.

As with every EightStar diamond, the American Star was cut using an exclusive light-tracking instrument called a 'FireScope' which allows cutters to align facets so precisely they can completely control the flow of light into and out of a diamond. "Without a Firescope, diamond cutting is guesswork," says Richard von Sternberg, EightStar's founder and president. "With it, our cutters look inside a diamond and fix fatal problems other cutters never even see."

After taking ten months for planning, including the design and manufacture of custom cutting equipment, the famous diamond was slowly recut from 14.89 to 13.42 carats over a six-week period in September-October 2001. "One reason for the slow grind is that EightStar cutters consult with the Firescope at every stage of work," von Sternberg notes. "Ordinarily, that means 200 Firescope checks. In the case of the American Star, however, I lost count at 500."
