Collecting and Classifying Coloured Diamonds: An Illustrated Study of the Aurora Collection

Hidden within the geological formations of our planet are some of the most unique and beautiful expressions of nature: fancy coloured diamonds. For centuries, these mysterious, exotic, and rare gemstones have been admired by connoisseurs, analyzed by gemologists, and coveted by collectors. Collecting and Classifying Coloured Diamonds, provides a detailed and handsomely illustrated account of these unusual gemstones.

Using the Aurora Collection of 260 fancy colour diamonds as its foundation, Collecting and Classifying Coloured Diamonds, explores the gamut of colours displayed by diamonds in nature and, in a format for both the layperson and the expert, investigates how diamond colours are perceived, measured, and classified. The Aurora Collection, considered one of the finest in the world, has been on exhibit at the American Museum of Natural History in New York since 1989.

Collecting and Classifying Coloured Diamonds was created to be a joy to look at, a pleasure to read, and a detailed reference for anyone interested in learning about nature's diverse expressions of colours in diamond. It will be of great interest to the general public as well as an indispensable tool for members of the diamond trade.

Collecting and Classifying Coloured Diamonds is also a valuable addition to libraries, institutions of higher learning, and an essential book for connoisseurs and collectors of coloured diamonds.

In addition to a comprehensive yet easy to read text, Collecting and Classifying Coloured Diamonds presents the reader with:

  • More than 700 colour photographs
  • More than 650 black and white diagrams
  • More than 300 quotations relating to coloured diamonds
  • Chart listing coloured diamonds on public exhibit
  • Charts denoting rarity for various diamond colours
  • Chart denoting highest prices for various colours
  • Chart denoting twelve colour varieties of diamond
  • More than 275 diamond colours classified
  • More than 560 terms defined in the glossary
  • More than 1200 books and articles referenced
  • More than 1400 coloured diamonds referenced

What People are Saying About This

Dimitris G. Minatidis

Stephen C. Hofer spending more than seven years investigating and writing on the topic has offered a book which is the result of a monumental amount of work, primarily by him and part contribution of Nick Hale of Hale Color Consultants, Inc., Naples, FL, USA and Tino Hammid of Tino Hammid Photography, Hollywood, CA, USA. The Aurora Collection, a collection of 260 natural coloured diamonds, was the backbone of the book and the spark for its creation. In a highly sophisticated way the book brings in the front of your eyes a perfect icon of the Aurora Collection coloured diamonds with 260 excellent color photos. In such a way the readers are experienced with the collection itself and have a Natural Standard Reference Set of coloured Diamonds to understand what the book says. The chapter Collecting Diamonds directs readers in collecting coloured diamonds a target that is not easy, as there are not many ways to collect such rarities. Apart from that what is impressive in this chapter is that the reader realizes that every coloured diamond is connected with an Event. While organizing a diamond collection by weight and size appears to be a simple process, organizing a diamond collection by color is more complex and hence more cumbersome. On the other hand to evaluate a diamond today, color must be taken into consideration. That is what this book is giving you: Using the Aurora Collection and knowing the Science of Color Stephen Hofer and contributors enable you to evaluate your colour diamonds in a very precise way. In a book I found in my personal Library LE DIAMENT, 1952 (in French) by Edmond Bruet, Payot, Paris, France 256 pages, color is taken into consideration in evaluating diamonds and 11 categories of coloured diamonds are reported. Going through the chapters of Collecting and Classifying Coloured Diamonds, Perception: The art of seeing colour, Grading: The Science of Specifying colour, Appearance: Defining Face-up colour, and Classification: Varieties, modifiers, tones, we <>. Sometimes we know complicate knowledge and we miss simple things. Sometimes we have our eyes open but we cannot see what we see. What is most important throughout that book is that every text is backed up by excellent colour photographs or diagrams. The Cut and colour Compendium section fills the proposed colour naming system for use in specifying coloured diamonds i.e. The universal Diamond Colour Language (UDCL). People say that if you know about 500 words of dialect you can communicate with the people of a Country. The Glossary of the book with more than 500 terms on colored diamonds will enable you to communicate with he inhabitants of the Coloured Diamond Country. The more than 700 large size pages, 700 colour photographs, 650 diagrams, 500 terms, the exhausted Bibliography and Auction Records beside other <>, going through its pages, makes that book a diachronic reference book on the topic for all involved in diamond, collection, classification, evaluation, gemology laboratories and Diamond Industry. I would strongly recommend that book to University Libraries and Mineralogical Museums around the World.
—Mr. Dimitris G. Minatidis (Oryktologika Nea News on Minerals Athens, Greece )


"...Using modern principles of colour science, Mr. Hofer offers a groundbreaking method for classifying coloured diamonds that brings the language and perception of coloured diamonds into the 21st century. ...The book contains twelve chapters. Chapter one provides an introduction to the Aurora Collection. Chapter two lists all 260 diamonds in the collection with a colour photograph of each stone and a simple guide for referencing basic data on a particular diamond. Technical information was kept to a minimum so that the readers can become familiar with the colour and beauty of each stone. Chapter three deals with collecting natural coloured diamonds. Chapter four talks about the rarity of these stones. Chapter five discusses the value of these stones. Chapter six handles the art of seeing colour. Chapter seven features grading, the science of specifying colour, while chapter eight deals with appearance: defining face-up colour. Chapter nine treats classification of the stones: varieties, modifiers, and tones. Classification is a very important discipline within the gemological sciences, especially within the subjects of mineralogy and gemology. The author therefore treats this very extensively in his book. Chapter ten, an appendix, provides a cut and colour compendium. Chapter eleven gives a glossary and chapter 12 features an extensive bibliography of books, articles ... This work is the ultimate reference for fancy coloured diamonds and will be a source of beauty and inspiration for anyone who appreciates natural coloured diamonds."
