"Gem and Ornamental Materials of Organic Origin" is a unique source of information on this neglected topic of gemmology. Presented in full colour, with over 200 stunning photographs for ease of reference and identification, the book allows material to be recognised by sight, avoiding the usual gemmological tests, which can ruin them. A comprehensive list of materials is included and each is presented with details or its origin, availability and conservation status. Examples of the uses of each material are given, along with a brief history of their use.
