Stephen C. Hofer
Stephen C. Hofer is considered to be the world's ranking technical and scientific authority on color measurement in colored diamonds.
In a business that is thousands of years old, Mr. Hofer is a modern pioneer. He has developed new ways of measuring color and color saturation. He developed a unique grading system for colored diamonds which is now universally recognized. An accomplished cutter himself, he encouraged and advanced the art and science of diamond-cutting for optimum color and has been an advisor to many owners of priceless rough colored diamonds. It is because of Mr. Hofer's influence that many skilled diamond cutters now strive to accentuate color even more than size and clarity.
He is the author of Collecting and Classifying colored Diamonds, the 800-page standard reference book for industry professionals and consumers alike, a book that is known for its scientific and technical insights. At PG Services, Mr. Hofer personally advises the firm and its suppliers. He is also an advisor to Christie's and Sotheby's New York as well as to many of the industry's most important dealers.
Mr. Hofer has published numerous technical papers and is a former columnist for New York Diamonds magazine. He lectures extensively and will embark on a series of international appearances, sponsored by PG Services.
