"I have had the pleasure of working with some of the most respected people in the diamond business including coloured diamond collectors, connoisseurs and private investors, diamond dealers and diamond cutters, jewelers (private and public), museum curators, and various auction houses. "
Stephen Hofer’s passion for studying colour was sparked at an early age. His many years of colour research have developed into a refined appreciation for the millions of subtle colour differences and combinations connected with nature. Mr. Hofer began his career in the earth sciences in 1976 as a geophysicist at the University of Connecticut. He studied gemology at the Gemological Institute of America (GIA) and the Gemological Association of Great Britain (GAGB), graduating with distinction. Mr. Hofer is also an accomplished diamond cutter, a graduate of the American Institute of Diamond Cutting (AIDC).
In 1979, Mr. Hofer accepted a position with the GIA Research Department; since then he has devoted his career to the study of coloured diamonds. He has published numerous technical papers, authored a quarterly column on coloured diamonds for New York Diamonds magazine, and published the comprehensive treatise, “COLLECTING AND CLASSIFYING COLOURED DIAMONDS”, a 760 page reference book considered to be the most important study of natural coloured diamonds to date.
