Sinkankas: A truly remarkable work and one of the major achievements in gemological literature of this century, affording as it does both a vast treasury of outstanding colored photographs of inclusions and remarks on same which explain their origin and significance. Such explanatory remarks appear in part one, and are followed in part two by succinct descriptions of geneses with contributions by Roedder, Meyer, and Stalder. Part three now treats inclusions themselves, ranging from amphibole to zircon, and also inclusions of glass, fluids, multiple inclusions, aggregates, and others of remarkable form or nature. Part four, the major part, treats the individual gem materials that host inclusions from amber to zoisite, and including phenomenal gemstones and rare species. Part five describes inclusions in man-made materials, mineralic, plastic, glass, etc. The references cited and general literature are by no means exhaustive and some major contributions by such as David Brewster and Isaac Lea are unaccountably absent.
