Gemological Institute of America writes:
The compelling story of man’s efforts to duplicate nature’s finest gems is told with style and expertise by Kurt Nassau, a pioneer in laser technology with twenty years laboratory experience in crystal growth. He relates the failures and successes of scientists who worked to create perfection—not mere gem imitations, but synthetic gemstones with the same chemical composition, crystal structure and appearance as naturally occurring diamonds, rubies, sapphires, emeralds, opals, and other precious stones.
The science of crystal growth is discussed with such clarity that Nassau conveys the excitement of analyzing and reproducing gemstones. First hand technical information and supportive date are provided for the crystal grower and mineralogist. In addition, a number of questions vital to the serious gem collector and the jeweler are answered. What are the causes of color in natural and synthetic gemstones? How can you distinguish natural stones from the many varieties of synthetic counterparts that now exist? What makes a synthetic created by one technique worth more in the marketplace than one created by another method? Will the duplication of nature’s gem affect the future marketplace for natural stones?
About the author
Dr Kurt Nassau is one of the very few persons who could have written the standard reference on gem synthesis. Best known as a pioneer in laser technology, he has worked in the field of crystal growth and solid state chemistry since 1959 as a research scientist at the Bell Laboratories in Murray Hill, New Jersey. He has 14 patents and has written over 200 technical publications and many articles for the Lapidary Journal, the American Mineralogist, and Gems and Gemology.
