Summary: Pt. 6: "This work is on the twelve gemstones in the breastplate of Aaron, the High Priest of the Jews, traditional founder of the Jewish priesthood, and it apparently is the first printed work to treat this subject."--Gemology by J. Sinkankas, entry no. 1906. Summary: Pt. 7: "...a compendium of past lore [relating to gemstones]...the origin of gems and their occult powers"--Gemology by J. Sinkankas, entry no. 5626. Summary: Pt. 8: "[T]his work is mainly of interest to the gemologist and mineralogist because it is essentially a compilation of information as then known, but largely free of lore and superstition.... The term "fossil" refers to anything dug form the ground... Gesner includes descriptions of many gemstones, some displaying crystal forms, others massive, and still others shown as cut gems... the preface states that this is the first book on a mineralogical subject so illustrated..."--Gemology by J. Sinkankas, entry no. 2366. A notable illustration shows a long-prismatic, rhombohedrally-terminated, and striated tourmaline crystal from Brazil labeled "smaragdus Bresilicus," or "Brazilian emerald," an unfortunate choice of term that was to be propagated in gemological literature for several centuries.--Gemology by J. Sinkankas, entry no. 2366. Each of the 3 pts. has separate dated title page and begins new pagination and register. All title pages bear publication date 1565.
