The Sinkankas Library

The world-renowned Sinkankas collection of books and other publications is now available to the public as part of the Richard T. Liddicoat Gemological Library and Information Center at GIA Santa Monica. Acquired by noted author and lapidary John Sinkankas and his wife Marjorie over the course of 40 years, the approximately 14,000 items include virtually all of the major works related to the study of gems and jewelry. This review of the important works in the Sinkankas library also serves to highlight the historical development of gemology – in art, in culture, and as a science.
