In 1987, after a second massive (2-year) full time commitment, Arem published the second edition of the COLOR ENCYCLOPEDIA. The new book had far better color reproduction than the first and more than 200 completely new photos. In addition, the text was 100 pages larger and included chapters on synthetic gemstones and thermal measurements. The second edition also contains the first comprehensive tabulation in the gemological literature of precise, machine generated measurements of the color of nearly all gemstone species and varieties. As the only full-color gemstone encyclopedia ever published, the Color Encyclopedia of Gemstones (2nd ed.) has often been called the most-used reference book in its field.
