The Color Encyclopedia of Gemstones has become the world's most widely referenced book on gems. Published in 1977, it was the first book to show, in photographs, the range of colors in gemstones and many rare collector stones that had never before been seen in print.
'gems and jewelry' was the first popular all-color mass market paperback guide to this subject. published by bantam books in 1975, it went on to sell more than 1 million copies and was translated into 4 languages. It was used as a textbook for many years by gemology schools and educators.
