GEM and Ornamental Materials of Organic Origin - Hardcover

'a particularly timely and very welcome addition to antiques literature...you could not want a more comprehensive or more clearly written guide to organic materials.

Although comprehensively illustrated in color, the success of a book like this relies above all on an ability to write with authority in an accessible, non-technical way. Maggie Campbell Pedersen is to be applauded for producing a volume of genuine use to dealers, collectors and museum curators.'
Antiques & Collectables, June 2004

A highly useful reference book, this is a unique source of information on a neglected topic of gemology. Two hundred color images are included for ease of reference and identification, allowing you to identify this material by sight, avoiding the usual gemological tests, which ruin them. - The Bead Forum, Newsletter of the Society of Bead Researchers

What an information laden reference book this is for gemologists, appraisers and collectors! While reading this book, I was impressed with the vast amount of information the author has gathered about each natural gem material.

There is a chapter dedicated to each organic material such as amber, jet, ivory, bone, antler, horn, tortoiseshell, pearls, shells, corals, baleen, byssus, calabash, coconut, feathers, hair, insect wings and other lesser known items.

She writes of the scientific examination of these items, the historical importance of these same items with references to the artistic and sometimes medicinal use of them.

I have not found a reference book that has more data on this subject. It is clearly written and illustrated with beautiful photographs. I found this book to be well organized, educational and valuable. I also enjoyed the non-technical way the identification and testing of these items is described. There are reference charts that aid in the separation of organic materials from simulants.

Since the book contains such a vast amount of information, it is a mandatory item for every gemologist appraiser's reference library. - National Association of Jewelry Appraisers magazine

The materials covered in the book include Amber and Copal; Jet; Ivory; Bone; Antler; Rhino horn; Horn; Tortoiseshell; Pearl; Shell; Coral, and other materials of plant and animal origin that have been used as gem or ornamental material. The book describes how to recognize them and how to distinguish them from the materials most commonly used to imitate them, for example plastic.

A comprehensive list of materials is included and each is presented with details of its origin, availability and conservation status, examples of, and a brief history of, their use. Organics fit together because of their origins, because they are constantly used together, have similar histories and were the earliest gem materials used.

200 color images are included for ease of reference and identification, allowing you to identify this material by sight, avoiding the usual gemological tests which ruin them.

Organics occur in modern and antique jewelry, in decorative items and in some furniture, and this book draws all the information together to provide the first complete overview of the subject.
