A serious book about identifying gemstones, written by two professional gemmologists.
Rather than work through a list of gemstones, there's a brief introduction to gemmology, then a list of gem testers, describing their features and limitations. The result is a complete set of instruction manuals for gem testers, a guide to the principles behind them...and by the time you've finished, you should be able to identify hundreds of gemstones.
