Keith Wallis’s informative guide book to understanding, identifying and buying gemstones
Mr Wallis is a qualified gemologist who obtained his diploma as a Fellow of the Gemological Association of Great Britain in 1978. He writes concisely and is clearly well travelled himself. His stated aim is to demystify the complex and he has succeeded in producing a book that encourages the beginner not to be put off by the minefield that awaits the buyer who is unprepared – particularly when buying abroad.
