The leading authority on emeralds

John Sinkankas' Emerald and Other Beryls is a must have have book for all gemologists. As Director of the Smithsonian Institute's Natural History Museum, Sinkankas' experience and knowledge on the subject is unsurpassable. As an emerald exporter myself, I have learned more about the characteristics of the gemstone from him than any other source I have looked into. Excellent information. A. Morales Bogota, Colombia
