Review
In 1987, a ninety-five point (0.95 ct) fancy purplish red sold for 8,315 per carat, or one hundred forty-five million dollars per ounce! At that point any lingering doubts about the value of rare natural coloured were erased, colored diamonds were not only the most expensive items on earth, their prices had entered outer space (i.e., this sale solidified natural coloured diamonds as the most concentrated form of wealth on the planet)!
According to many industry experts (e.g., Dr. J. Arem, author of the highly acclaimed Color Encyclopedia of Gemstones), Stephen Hofer’s book is the most comprehensive book ever written on colored diamonds. To call Hofer’s book comprehensive is, in fact, something of an understatement. Collecting and Classifying Coloured Diamonds ranks not only as a definitive treatment of colored diamonds, it also contains one of the most interesting and relevant essays on the subject of color perception and colour science as it relates to gemstones yet published.
The major theme of Collecting and Classifying Coloured Diamonds is a thorough study of the famous Aurora Collection of colored diamonds. Along the way, Hofer also offers a logical new approach to colored diamond grading and a simple color classification system (referred to as the Universal Diamond Colour Language, UDCL), which includes a new short-hand method of colour notation (e.g., bluish green = b-G, blue-green = B-G, grayish blue-green = gy-B-G), and an excellent essay on gemstone lighting and its effect on colour appearance.
