Gemstones of North America provides the most authoritative and comprehensive reference ever published on North American gemstones and localities. The principal emphasis is laid upon what gemstones are to be found in North America, their properties and appearance, and where and in what quantity and quality they occur. 176 drawings, diagrams, maps, photographs and color plates serve to illustrate and enhance the text. Assembled in this book are those facts which will be most useful to students, collectors and connoisseurs of gems, museums, and of course to the host of jewelry makers whose interest in native gemstones encourages the development of gemstone resources. John Sinkankas authored this reference for scientifically minded readers. Held to a minimum are aspects of curious lore involving superstitions, alleged medicinal properties and other exotic attributes of gems.

Gemstones of North America is organized into seven major chapters. The first chapter deals with the essential nature of gemstones and discusses the essential physical properties and features which make gemstones objects of beauty. Technical terms and gemstone terminology employed throughout the remainder of the book are explained for the average reader lacking formal education in mineralogy and the Earth sciences. Succeeding chapters take up individual gemstone species. The major scientific aspects of each are covered, especially in connection with varieties that yield gemstones. Every species discussion begins with a brief explanation of the gemstone, its scientific name, varietal names, and other useful data, followed by a section dealing with the physical, chemical and optical properties of the species. Further discussion elaborates upon color, quality and other features which add or detract from its value as a gemstone or affect its commercial importance. At the close of each species description, localities are described beginning with those in the northernmost lands and finishing with places in Central America and the West Indies. Information on the features of mineralogy and geology of the gemstone deposits is also furnished. The arrangement of species within the body of the book takes reflects their commercial importance, abundance or rarity, their specific uses in jewelry and ornamentation, and brings together those which are closely related in some important respect. An entire 113 page chapter is devoted to the quartz of family gemstones, presenting an exhaustive description of quartz gemstone varieties.
