How does a jeweler tell a real gem from a clever fake? Frank Wade teaches the tests, lesson by lesson: how stones differ, how light refracts and doubles inside them, and what the eye and instrument reveal. A practical education for the gem-loving public. Learn to judge a stone the way an expert does.

Every copy includes a printable PDF edition, a beautifully typeset book you can print, mark up in the margins, and keep on your shelf. Yours the moment you own it.
