Gemstone & Mineral Data Book by John Sinkankas. A great vintage hardback book. Per the cover, "A unique compilation in one handy volume of hard-to-find data, formulas, compounds, tables, properties - including instructions on cleaning and preserving methods for over 1000 mineral species - for the mineralogist, gemologist, lapidary, jeweler, craftsman and collector." Copyright 1972. I believe this to be a first edition.
The book is in wonderful condition. The pages are crisp and clean, spine is tight. The dust jacket is in good condition, there is typical shelf wear (fine lines and scratches present), and dings/creases along the edges.
